Although this patch creates a separate\nflavor of RCU for ease of review and patch maintenance, it is intended\nto replace classic RCU.\n\nThis patch still handles stress better than does mainline, so I am still\ncalling it ready for inclusion.  This patch is against the -tip tree.\nNevertheless, experience on an actual 1000+ CPU machine would still be\nmost welcome.\n\nMost of the changes noted below were found while creating an rcutiny\n(which should permit ejecting the current rcuclassic) and while doing\ndetailed line-by-line documentation.\n\nUpdates from v9 (http://lkml.org/lkml/2008/12/2/334):\n\no\tFixes from remainder of line-by-line code walkthrough,\n\tincluding comment spelling, initialization, undesirable\n\tnarrowing due to type conversion, removing redundant memory\n\tbarriers, removing redundant local-variable initialization,\n\tand removing redundant local variables.\n\n\tI do not believe that any of these fixes address the CPU-hotplug\n\tissues that Andi Kleen was seeing, but please do give it a whirl\n\tin case the machine is smarter than I am.\n\n\tA writeup from the walkthrough may be found at the following\n\tURL, in case you are suffering from terminal insomnia or\n\tmasochism:\n\n\thttp://www.kernel.org/pub/linux/kernel/people/paulmck/tmp/rcutree-walkthrough.2008.12.16a.pdf\n\no\tMade rcutree tracing use seq_file, as suggested some time\n\tago by Lai Jiangshan.\n\no\tAdded a .csv variant of the rcudata debugfs trace file, to allow\n\tpeople having thousands of CPUs to drop the data into\n\ta spreadsheet.\tTested with oocalc and gnumeric.  Updated\n\tdocumentation to suit.\n\nUpdates from v8 (http://lkml.org/lkml/2008/11/15/139):\n\no\tFix a theoretical race between grace-period initialization and\n\tforce_quiescent_state() that could occur if more than three\n\tjiffies were required to carry out the grace-period\n\tinitialization.  Which it might, if you had enough CPUs.\n\no\tApply Ingo\u0027s printk-standardization patch.\n\no\tSubstitute local variables for repeated accesses to global\n\tvariables.\n\no\tFix comment misspellings and redundant (but harmless) increments\n\tof -\u003en_rcu_pending (this latter after having explicitly added it).\n\no\tApply checkpatch fixes.\n\nUpdates from v7 (http://lkml.org/lkml/2008/10/10/291):\n\no\tFixed a number of problems noted by Gautham Shenoy, including\n\tthe cpu-stall-detection bug that he was having difficulty\n\tconvincing me was real.  ;-)\n\no\tChanged cpu-stall detection to wait for ten seconds rather than\n\tthree in order to reduce false positive, as suggested by Ingo\n\tMolnar.\n\no\tProduced a design document (http://lwn.net/Articles/305782/).\n\tThe act of writing this document uncovered a number of both\n\ttheoretical and \"here and now\" bugs as noted below.\n\no\tFix dynticks_nesting accounting confusion, simplify WARN_ON()\n\tcondition, fix kerneldoc comments, and add memory barriers\n\tin dynticks interface functions.\n\no\tAdd more data to tracing.\n\no\tRemove unused \"rcu_barrier\" field from rcu_data structure.\n\no\tCount calls to rcu_pending() from scheduling-clock interrupt\n\tto use as a surrogate timebase should jiffies stop counting.\n\no\tFix a theoretical race between force_quiescent_state() and\n\tgrace-period initialization.  Yes, initialization does have to\n\tgo on for some jiffies for this race to occur, but given enough\n\tCPUs...\n\nUpdates from v6 (http://lkml.org/lkml/2008/9/23/448):\n\no\tFix a number of checkpatch.pl complaints.\n\no\tApply review comments from Ingo Molnar and Lai Jiangshan\n\ton the stall-detection code.\n\no\tFix several bugs in !CONFIG_SMP builds.\n\no\tFix a misspelled config-parameter name so that RCU now announces\n\tat boot time if stall detection is configured.\n\no\tRun tests on numerous combinations of configurations parameters,\n\twhich after the fixes above, now build and run correctly.\n\nUpdates from v5 (http://lkml.org/lkml/2008/9/15/92, bad subject line):\n\no\tFix a compiler error in the !CONFIG_FANOUT_EXACT case (blew a\n\tchangeset some time ago, and finally got around to retesting\n\tthis option).\n\no\tFix some tracing bugs in rcupreempt that caused incorrect\n\ttotals to be printed.\n\no\tI now test with a more brutal random-selection online/offline\n\tscript (attached).  Probably more brutal than it needs to be\n\ton the people reading it as well, but so it goes.\n\no\tA number of optimizations and usability improvements:\n\n\to\tMake rcu_pending() ignore the grace-period timeout when\n\t\tthere is no grace period in progress.\n\n\to\tMake force_quiescent_state() avoid going for a global\n\t\tlock in the case where there is no grace period in\n\t\tprogress.\n\n\to\tRearrange struct fields to improve struct layout.\n\n\to\tMake call_rcu() initiate a grace period if RCU was\n\t\tidle, rather than waiting for the next scheduling\n\t\tclock interrupt.\n\n\to\tInvoke rcu_irq_enter() and rcu_irq_exit() only when\n\t\tidle, as suggested by Andi Kleen.  I still don\u0027t\n\t\tcompletely trust this change, and might back it out.\n\n\to\tMake CONFIG_RCU_TRACE be the single config variable\n\t\tmanipulated for all forms of RCU, instead of the prior\n\t\tconfusion.\n\n\to\tDocument tracing files and formats for both rcupreempt\n\t\tand rcutree.\n\nUpdates from v4 for those missing v5 given its bad subject line:\n\no\tSeparated dynticks interface so that NMIs and irqs call separate\n\tfunctions, greatly simplifying it.  In particular, this code\n\tno longer requires a proof of correctness.  ;-)\n\no\tSeparated dynticks state out into its own per-CPU structure,\n\tavoiding the duplicated accounting.\n\no\tThe case where a dynticks-idle CPU runs an irq handler that\n\tinvokes call_rcu() is now correctly handled, forcing that CPU\n\tout of dynticks-idle mode.\n\no\tReview comments have been applied (thank you all!!!).\n\tFor but one example, fixed the dynticks-ordering issue that\n\tManfred pointed out, saving me much debugging.  ;-)\n\no\tAdjusted rcuclassic and rcupreempt to handle dynticks changes.\n\nAttached is an updated patch to Classic RCU that applies a hierarchy,\ngreatly reducing the contention on the top-level lock for large machines.\nThis passes 10-hour concurrent rcutorture and online-offline testing on\n128-CPU ppc64 without dynticks enabled, and exposes some timekeeping\nbugs in presence of dynticks (exciting working on a system where\n\"sleep 1\" hangs until interrupted...), which were fixed in the\n2.6.27 kernel.  It is getting more reliable than mainline by some\nmeasures, so the next version will be against -tip for inclusion.\nSee also Manfred Spraul\u0027s recent patches (or his earlier work from\n2004 at http://marc.info/?l\u003dlinux-kernel\u0026m\u003d108546384711797\u0026w\u003d2).\nWe will converge onto a common patch in the fullness of time, but are\ncurrently exploring different regions of the design space.  That said,\nI have already gratefully stolen quite a few of Manfred\u0027s ideas.\n\nThis patch provides CONFIG_RCU_FANOUT, which controls the bushiness\nof the RCU hierarchy.  Defaults to 32 on 32-bit machines and 64 on\n64-bit machines.  If CONFIG_NR_CPUS is less than CONFIG_RCU_FANOUT,\nthere is no hierarchy.  By default, the RCU initialization code will\nadjust CONFIG_RCU_FANOUT to balance the hierarchy, so strongly NUMA\narchitectures may choose to set CONFIG_RCU_FANOUT_EXACT to disable\nthis balancing, allowing the hierarchy to be exactly aligned to the\nunderlying hardware.  Up to two levels of hierarchy are permitted\n(in addition to the root node), allowing up to 16,384 CPUs on 32-bit\nsystems and up to 262,144 CPUs on 64-bit systems.  I just know that I\nam going to regret saying this, but this seems more than sufficient\nfor the foreseeable future.  (Some architectures might wish to set\nCONFIG_RCU_FANOUT\u003d4, which would limit such architectures to 64 CPUs.\nIf this becomes a real problem, additional levels can be added, but I\ndoubt that it will make a significant difference on real hardware.)\n\nIn the common case, a given CPU will manipulate its private rcu_data\nstructure and the rcu_node structure that it shares with its immediate\nneighbors.  This can reduce both lock and memory contention by multiple\norders of magnitude, which should eliminate the need for the strange\nmanipulations that are reported to be required when running Linux on\nvery large systems.\n\nSome shortcomings:\n\no\tMore bugs will probably surface as a result of an ongoing\n\tline-by-line code inspection.\n\n\tPatches will be provided as required.\n\no\tThere are probably hangs, rcutorture failures, \u0026c.  Seems\n\tquite stable on a 128-CPU machine, but that is kind of small\n\tcompared to 4096 CPUs.  However, seems to do better than\n\tmainline.\n\n\tPatches will be provided as required.\n\no\tThe memory footprint of this version is several KB larger\n\tthan rcuclassic.\n\n\tA separate UP-only rcutiny patch will be provided, which will\n\treduce the memory footprint significantly, even compared\n\tto the old rcuclassic.  One such patch passes light testing,\n\tand has a memory footprint smaller even than rcuclassic.\n\tInitial reaction from various embedded guys was \"it is not\n\tworth it\", so am putting it aside.\n\nCredits:\n\no\tManfred Spraul for ideas, review comments, and bugs spotted,\n\tas well as some good friendly competition.  ;-)\n\no\tJosh Triplett, Ingo Molnar, Peter Zijlstra, Mathieu Desnoyers,\n\tLai Jiangshan, Andi Kleen, Andy Whitcroft, and Andrew Morton\n\tfor reviews and comments.\n\no\tThomas Gleixner for much-needed help with some timer issues\n\t(see patches below).\n\no\tJon M.

      "message": "container freezer: implement freezer cgroup subsystem\n\nThis patch implements a new freezer subsystem in the control groups\nframework.  It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state.  Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup.  Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup.  Reading will return the current state.\n\n* Examples of usage :\n\n   # mkdir /containers/freezer\n   # mount -t cgroup -ofreezer freezer  /containers\n   # mkdir /containers/0\n   # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n   # cat /containers/0/freezer.state\n   RUNNING\n\nto freeze all tasks in the container :\n\n   # echo FROZEN \u003e /containers/0/freezer.state\n   # cat /containers/0/freezer.state\n   FREEZING\n   # cat /containers/0/freezer.state\n   FROZEN\n\nto unfreeze all tasks in the container :\n\n   # echo RUNNING \u003e /containers/0/freezer.state\n   # cat /containers/0/freezer.state\n   RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete.  In that case we\nreturn EBUSY.  This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime.  After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read.  The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.

      "message": "tracing: Kernel Tracepoints\n\nImplementation of kernel tracepoints. Inspired from the Linux Kernel\nMarkers. Allows complete typing verification by declaring both tracing\nstatement inline functions and probe registration/unregistration static\ninline functions within the same macro \"DEFINE_TRACE\". No format string\nis required. See the tracepoint Documentation and Samples patches for\nusage examples.\n\nTaken from the documentation patch :\n\n\"A tracepoint placed in code provides a hook to call a function (probe)\nthat you can provide at runtime. A tracepoint can be \"on\" (a probe is\nconnected to it) or \"off\" (no probe is attached). When a tracepoint is\n\"off\" it has no effect, except for adding a tiny time penalty (checking\na condition for a branch) and space penalty (adding a few bytes for the\nfunction call at the end of the instrumented function and adds a data\nstructure in a separate section).  When a tracepoint is \"on\", the\nfunction you provide is called each time the tracepoint is executed, in\nthe execution context of the caller. When the function provided ends its\nexecution, it returns to the caller (continuing from the tracepoint\nsite).\n\nYou can put tracepoints at important locations in the code. They are\nlightweight hooks that can pass an arbitrary number of parameters, which\nprototypes are described in a tracepoint declaration placed in a header\nfile.\"\n\nAddition and removal of tracepoints is synchronized by RCU using the\nscheduler (and preempt_disable) as guarantees to find a quiescent state\n(this is really RCU \"classic\"). The update side uses rcu_barrier_sched()\nwith call_rcu_sched() and the read/execute side uses\n\"preempt_disable()/preempt_enable()\".\n\nWe make sure the previous array containing probes, which has been\nscheduled for deletion by the rcu callback, is indeed freed before we\nproceed to the next update. It therefore limits the rate of modification\nof a single tracepoint to one update per RCU period. The objective here\nis to permit fast batch add/removal of probes on _different_\ntracepoints.\n\nChangelog :\n- Use #name \":\" #proto as string to identify the tracepoint in the\n  tracepoint table. This will make sure not type mismatch happens due to\n  connexion of a probe with the wrong type to a tracepoint declared with\n  the same name in a different header.\n- Add tracepoint_entry_free_old.\n- Change __TO_TRACE to get rid of the \u0027i\u0027 iterator.\n\nMasami Hiramatsu \u003cmhiramat@redhat.com\u003e :\nTested on x86-64.\n\nPerformance impact of a tracepoint : same as markers, except that it\nadds about 70 bytes of instructions in an unlikely branch of each\ninstrumented function (the for loop, the stack setup and the function\ncall). It currently adds a memory read, a test and a conditional branch\nat the instrumentation site (in the hot path). Immediate values will\neventually change this into a load immediate, test and branch, which\nremoves the memory read which will make the i-cache impact smaller\n(changing the memory read for a load immediate removes 3-4 bytes per\nsite on x86_32 (depending on mov prefixes), or 7-8 bytes on x86_64, it\nalso saves the d-cache hit).\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added.\n\nQuoting Hideo Aoki about Markers :\n\nI evaluated overhead of kernel marker using linux-2.6-sched-fixes git\ntree, which includes several markers for LTTng, using an ia64 server.\n\nWhile the immediate trace mark feature isn\u0027t implemented on ia64, there\nis no major performance regression. So, I think that we don\u0027t have any\nissues to propose merging marker point patches into Linus\u0027s tree from\nthe viewpoint of performance impact.\n\nI prepared two kernels to evaluate. The first one was compiled without\nCONFIG_MARKERS. The second one was enabled CONFIG_MARKERS.\n\nI downloaded the original hackbench from the following URL:\nhttp://devresources.linux-foundation.org/craiger/hackbench/src/hackbench.c\n\nI ran hackbench 5 times in each condition and calculated the average and\ndifference between the kernels.\n\n    The parameter of hackbench: every 50 from 50 to 800\n    The number of CPUs of the server: 2, 4, and 8\n\nBelow is the results. As you can see, major performance regression\nwasn\u0027t found in any case. Even if number of processes increases,\ndifferences between marker-enabled kernel and marker- disabled kernel\ndoesn\u0027t increase. Moreover, if number of CPUs increases, the differences\ndoesn\u0027t increase either.\n\nCuriously, marker-enabled kernel is better than marker-disabled kernel\nin more than half cases, although I guess it comes from the difference\nof memory access pattern.\n\n* 2 CPUs\n\nNumber of | without      | with         | diff     | diff    |\nprocesses | Marker [Sec] | Marker [Sec] |   [Sec]  |   [%]   |\n--------------------------------------------------------------\n       50 |      4.811   |       4.872  |  +0.061  |  +1.27  |\n      100 |      9.854   |      10.309  |  +0.454  |  +4.61  |\n      150 |     15.602   |      15.040  |  -0.562  |  -3.6   |\n      200 |     20.489   |      20.380  |  -0.109  |  -0.53  |\n      250 |     25.798   |      25.652  |  -0.146  |  -0.56  |\n      300 |     31.260   |      30.797  |  -0.463  |  -1.48  |\n      350 |     36.121   |      35.770  |  -0.351  |  -0.97  |\n      400 |     42.288   |      42.102  |  -0.186  |  -0.44  |\n      450 |     47.778   |      47.253  |  -0.526  |  -1.1   |\n      500 |     51.953   |      52.278  |  +0.325  |  +0.63  |\n      550 |     58.401   |      57.700  |  -0.701  |  -1.2   |\n      600 |     63.334   |      63.222  |  -0.112  |  -0.18  |\n      650 |     68.816   |      68.511  |  -0.306  |  -0.44  |\n      700 |     74.667   |      74.088  |  -0.579  |  -0.78  |\n      750 |     78.612   |      79.582  |  +0.970  |  +1.23  |\n      800 |     85.431   |      85.263  |  -0.168  |  -0.2   |\n--------------------------------------------------------------\n\n* 4 CPUs\n\nNumber of | without      | with         | diff     | diff    |\nprocesses | Marker [Sec] | Marker [Sec] |   [Sec]  |   [%]   |\n--------------------------------------------------------------\n       50 |      2.586   |       2.584  |  -0.003  |  -0.1   |\n      100 |      5.254   |       5.283  |  +0.030  |  +0.56  |\n      150 |      8.012   |       8.074  |  +0.061  |  +0.76  |\n      200 |     11.172   |      11.000  |  -0.172  |  -1.54  |\n      250 |     13.917   |      14.036  |  +0.119  |  +0.86  |\n      300 |     16.905   |      16.543  |  -0.362  |  -2.14  |\n      350 |     19.901   |      20.036  |  +0.135  |  +0.68  |\n      400 |     22.908   |      23.094  |  +0.186  |  +0.81  |\n      450 |     26.273   |      26.101  |  -0.172  |  -0.66  |\n      500 |     29.554   |      29.092  |  -0.461  |  -1.56  |\n      550 |     32.377   |      32.274  |  -0.103  |  -0.32  |\n      600 |     35.855   |      35.322  |  -0.533  |  -1.49  |\n      650 |     39.192   |      38.388  |  -0.804  |  -2.05  |\n      700 |     41.744   |      41.719  |  -0.025  |  -0.06  |\n      750 |     45.016   |      44.496  |  -0.520  |  -1.16  |\n      800 |     48.212   |      47.603  |  -0.609  |  -1.26  |\n--------------------------------------------------------------\n\n* 8 CPUs\n\nNumber of | without      | with         | diff     | diff    |\nprocesses | Marker [Sec] | Marker [Sec] |   [Sec]  |   [%]   |\n--------------------------------------------------------------\n       50 |      2.094   |       2.072  |  -0.022  |  -1.07  |\n      100 |      4.162   |       4.273  |  +0.111  |  +2.66  |\n      150 |      6.485   |       6.540  |  +0.055  |  +0.84  |\n      200 |      8.556   |       8.478  |  -0.078  |  -0.91  |\n      250 |     10.458   |      10.258  |  -0.200  |  -1.91  |\n      300 |     12.425   |      12.750  |  +0.325  |  +2.62  |\n      350 |     14.807   |      14.839  |  +0.032  |  +0.22  |\n      400 |     16.801   |      16.959  |  +0.158  |  +0.94  |\n      450 |     19.478   |      19.009  |  -0.470  |  -2.41  |\n      500 |     21.296   |      21.504  |  +0.208  |  +0.98  |\n      550 |     23.842   |      23.979  |  +0.137  |  +0.57  |\n      600 |     26.309   |      26.111  |  -0.198  |  -0.75  |\n      650 |     28.705   |      28.446  |  -0.259  |  -0.9   |\n      700 |     31.233   |      31.394  |  +0.161  |  +0.52  |\n      750 |     34.064   |      33.720  |  -0.344  |  -1.01  |\n      800 |     36.320   |      36.114  |  -0.206  |  -0.57  |\n--------------------------------------------------------------\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@polymtl.ca\u003e\nAcked-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nAcked-by: \u0027Peter Zijlstra\u0027 \u003cpeterz@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "avoid overflows in kernel/time.c\n\nWhen the conversion factor between jiffies and milli- or microseconds is\nnot a single multiply or divide, as for the case of HZ \u003d\u003d 300, we currently\ndo a multiply followed by a divide.  The intervening result, however, is\nsubject to overflows, especially since the fraction is not simplified (for\nHZ \u003d\u003d 300, we multiply by 300 and divide by 1000).\n\nThis is exposed to the user when passing a large timeout to poll(), for\nexample.\n\nThis patch replaces the multiply-divide with a reciprocal multiplication on\n32-bit platforms.  When the input is an unsigned long, there is no portable\nway to do this on 64-bit platforms there is no portable way to do this\nsince it requires a 128-bit intermediate result (which gcc does support on\n64-bit platforms but may generate libgcc calls, e.g.  on 64-bit s390), but\nsince the output is a 32-bit integer in the cases affected, just simplify\nthe multiply-divide (*3/10 instead of *300/1000).\n\nThe reciprocal multiply used can have off-by-one errors in the upper half\nof the valid output range.  This could be avoided at the expense of having\nto deal with a potential 65-bit intermediate result.  Since the intent is\nto avoid overflow problems and most of the other time conversions are only\nsemiexact, the off-by-one errors were considered an acceptable tradeoff.\n\nAt Ralf Baechle\u0027s suggestion, this version uses a Perl script to compute\nthe necessary constants.  We already have dependencies on Perl for kernel\ncompiles.  This does, however, require the Perl module Math::BigInt, which\nis included in the standard Perl distribution starting with version 5.8.0.\nIn order to support older versions of Perl, include a table of canned\nconstants in the script itself, and structure the script so that\nMath::BigInt isn\u0027t required if pulling values from said table.\n\nRunning the script requires that the HZ value is available from the\nMakefile.  Thus, this patch also adds the Kconfig variable CONFIG_HZ to the\narchitectures which didn\u0027t already have it (alpha, cris, frv, h8300, m32r,\nm68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or\nsh64 architectures, since Paul Mundt has dealt with those separately in the\nsh tree.\n\nSigned-off-by: H.

      "message": "pm qos infrastructure and interface\n\nThe following patch is a generalization of the latency.c implementation done\nby Arjan last year.  It provides infrastructure for more than one parameter,\nand exposes a user mode interface for processes to register pm_qos\nexpectations of processes.\n\nThis interface provides a kernel and user mode interface for registering\nperformance expectations by drivers, subsystems and user space applications on\none of the parameters.\n\nCurrently we have {cpu_dma_latency, network_latency, network_throughput} as\nthe initial set of pm_qos parameters.\n\nThe infrastructure exposes multiple misc device nodes one per implemented\nparameter.  The set of parameters implement is defined by pm_qos_power_init()\nand pm_qos_params.h.  This is done because having the available parameters\nbeing runtime configurable or changeable from a driver was seen as too easy to\nabuse.\n\nFor each parameter a list of performance requirements is maintained along with\nan aggregated target value.  The aggregated target value is updated with\nchanges to the requirement list or elements of the list.  Typically the\naggregated target value is simply the max or min of the requirement values\nheld in the parameter list elements.\n\n\u003eFrom kernel mode the use of this interface is simple:\n\npm_qos_add_requirement(param_id, name, target_value):\n\n  Will insert a named element in the list for that identified PM_QOS\n  parameter with the target value.  Upon change to this list the new target is\n  recomputed and any registered notifiers are called only if the target value\n  is now different.\n\npm_qos_update_requirement(param_id, name, new_target_value):\n\n  Will search the list identified by the param_id for the named list element\n  and then update its target value, calling the notification tree if the\n  aggregated target is changed.  with that name is already registered.\n\npm_qos_remove_requirement(param_id, name):\n\n  Will search the identified list for the named element and remove it, after\n  removal it will update the aggregate target and call the notification tree\n  if the target was changed as a result of removing the named requirement.\n\n\u003eFrom user mode:\n\n  Only processes can register a pm_qos requirement.  To provide for\n  automatic cleanup for process the interface requires the process to register\n  its parameter requirements in the following way:\n\n  To register the default pm_qos target for the specific parameter, the\n  process must open one of /dev/[cpu_dma_latency, network_latency,\n  network_throughput]\n\n  As long as the device node is held open that process has a registered\n  requirement on the parameter.  The name of the requirement is\n  \"process_\u003cPID\u003e\" derived from the current-\u003epid from within the open system\n  call.\n\n  To change the requested target value the process needs to write a s32\n  value to the open device node.  This translates to a\n  pm_qos_update_requirement call.\n\n  To remove the user mode request for a target value simply close the device\n  node.\n\n[akpm@linux-foundation.org: fix warnings]\n[akpm@linux-foundation.org: fix build]\n[akpm@linux-foundation.org: fix build again]\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: mark gross \u003cmgross@linux.intel.com\u003e\nCc: \"John W.

      "message": "Task Control Groups: basic task cgroup framework\n\nGeneric Process Control Groups\n--------------------------\n\nThere have recently been various proposals floating around for\nresource management/accounting and other task grouping subsystems in\nthe kernel, including ResGroups, User BeanCounters, NSProxy\ncgroups, and others.  These all need the basic abstraction of being\nable to group together multiple processes in an aggregate, in order to\ntrack/limit the resources permitted to those processes, or control\nother behaviour of the processes, and all implement this grouping in\ndifferent ways.\n\nThis patchset provides a framework for tracking and grouping processes\ninto arbitrary \"cgroups\" and assigning arbitrary state to those\ngroupings, in order to control the behaviour of the cgroup as an\naggregate.\n\nThe intention is that the various resource management and\nvirtualization/cgroup efforts can also become task cgroup\nclients, with the result that:\n\n- the userspace APIs are (somewhat) normalised\n\n- it\u0027s easier to test e.g. the ResGroups CPU controller in\n conjunction with the BeanCounters memory controller, or use either of\nthem as the resource-control portion of a virtual server system.\n\n- the additional kernel footprint of any of the competing resource\n management systems is substantially reduced, since it doesn\u0027t need\n to provide process grouping/containment, hence improving their\n chances of getting into the kernel\n\nThis patch:\n\nAdd the main task cgroups framework - the cgroup filesystem, and the\nbasic structures for tracking membership and associating subsystem state\nobjects to tasks.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Serge E.

      "message": "[PATCH] srcu-3: RCU variant permitting read-side blocking\n\nUpdated patch adding a variant of RCU that permits sleeping in read-side\ncritical sections.  SRCU is as follows:\n\no\tEach use of SRCU creates its own srcu_struct, and each\n\tsrcu_struct has its own set of grace periods.  This is\n\tcritical, as it prevents one subsystem with a blocking\n\treader from holding up SRCU grace periods for other\n\tsubsystems.\n\no\tThe SRCU primitives (srcu_read_lock(), srcu_read_unlock(),\n\tand synchronize_srcu()) all take a pointer to a srcu_struct.\n\no\tThe SRCU primitives must be called from process context.\n\no\tsrcu_read_lock() returns an int that must be passed to\n\tthe matching srcu_read_unlock().  Realtime RCU avoids the\n\tneed for this by storing the state in the task struct,\n\tbut SRCU needs to allow a given code path to pass through\n\tmultiple SRCU domains -- storing state in the task struct\n\twould therefore require either arbitrary space in the\n\ttask struct or arbitrary limits on SRCU nesting.  So I\n\tkicked the state-storage problem up to the caller.\n\n\tOf course, it is not permitted to call synchronize_srcu()\n\twhile in an SRCU read-side critical section.\n\no\tThere is no call_srcu().  It would not be hard to implement\n\tone, but it seems like too easy a way to OOM the system.\n\t(Hey, we have enough trouble with call_rcu(), which does\n\t-not- permit readers to sleep!!!)

      "message": "[PATCH] maximum latency tracking infrastructure\n\nAdd infrastructure to track \"maximum allowable latency\" for power saving\npolicies.\n\nThe reason for adding this infrastructure is that power management in the\nidle loop needs to make a tradeoff between latency and power savings\n(deeper power save modes have a longer latency to running code again).  The\ncode that today makes this tradeoff just does a rather simple algorithm;\nhowever this is not good enough: There are devices and use cases where a\nlower latency is required than that the higher power saving states provide.\n An example would be audio playback, but another example is the ipw2100\nwireless driver that right now has a very direct and ugly acpi hook to\ndisable some higher power states randomly when it gets certain types of\nerror.\n\nThe proposed solution is to have an interface where drivers can\n\n* announce the maximum latency (in microseconds) that they can deal with\n* modify this latency\n* give up their constraint\n\nand a function where the code that decides on power saving strategy can\nquery the current global desired maximum.\n\nThis patch has a user of each side: on the consumer side, ACPI is patched\nto use this, on the producer side the ipw2100 driver is patched.\n\nA generic maximum latency is also registered of 2 timer ticks (more and you\nlose accurate time tracking after all).\n\nWhile the existing users of the patch are x86 specific, the infrastructure\nis not.  I\u0027d like to ask the arch maintainers of other architectures if the\ninfrastructure is generic enough for their use (assuming the architecture\nhas such a tradeoff as concept at all), and the sound/multimedia driver\nowners to look at the driver facing API to see if this is something they\ncan use.\n\n[akpm@osdl.org: cleanups]\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Jesse Barnes \u003cjesse.barnes@intel.com\u003e\nCc: \"Brown, Len\" \u003clen.brown@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] lockdep: core\n\nDo \u0027make oldconfig\u0027 and accept all the defaults for new config options -\nreboot into the kernel and if everything goes well it should boot up fine and\nyou should have /proc/lockdep and /proc/lockdep_stats files.\n\nTypically if the lock validator finds some problem it will print out\nvoluminous debug output that begins with \"BUG: ...\" and which syslog output\ncan be used by kernel developers to figure out the precise locking scenario.\n\nWhat does the lock validator do?  It \"observes\" and maps all locking rules as\nthey occur dynamically (as triggered by the kernel\u0027s natural use of spinlocks,\nrwlocks, mutexes and rwsems).  Whenever the lock validator subsystem detects a\nnew locking scenario, it validates this new rule against the existing set of\nrules.  If this new rule is consistent with the existing set of rules then the\nnew rule is added transparently and the kernel continues as normal.  If the\nnew rule could create a deadlock scenario then this condition is printed out.\n\nWhen determining validity of locking, all possible \"deadlock scenarios\" are\nconsidered: assuming arbitrary number of CPUs, arbitrary irq context and task\ncontext constellations, running arbitrary combinations of all the existing\nlocking scenarios.  In a typical system this means millions of separate\nscenarios.  This is why we call it a \"locking correctness\" validator - for all\nrules that are observed the lock validator proves it with mathematical\ncertainty that a deadlock could not occur (assuming that the lock validator\nimplementation itself is correct and its internal data structures are not\ncorrupted by some other kernel subsystem).  [see more details and conditionals\nof this statement in include/linux/lockdep.h and\nDocumentation/lockdep-design.txt]\n\nFurthermore, this \"all possible scenarios\" property of the validator also\nenables the finding of complex, highly unlikely multi-CPU multi-context races\nvia single single-context rules, increasing the likelyhood of finding bugs\ndrastically.  In practical terms: the lock validator already found a bug in\nthe upstream kernel that could only occur on systems with 3 or more CPUs, and\nwhich needed 3 very unlikely code sequences to occur at once on the 3 CPUs.\nThat bug was found and reported on a single-CPU system (!).  So in essence a\nrace will be found \"piecemail-wise\", triggering all the necessary components\nfor the race, without having to reproduce the race scenario itself!  In its\nshort existence the lock validator found and reported many bugs before they\nactually caused a real deadlock.\n\nTo further increase the efficiency of the validator, the mapping is not per\n\"lock instance\", but per \"lock-class\".  For example, all struct inode objects\nin the kernel have inode-\u003einotify_mutex.  If there are 10,000 inodes cached,\nthen there are 10,000 lock objects.  But -\u003einotify_mutex is a single \"lock\ntype\", and all locking activities that occur against -\u003einotify_mutex are\n\"unified\" into this single lock-class.  The advantage of the lock-class\napproach is that all historical -\u003einotify_mutex uses are mapped into a single\n(and as narrow as possible) set of locking rules - regardless of how many\ndifferent tasks or inode structures it took to build this set of rules.  The\nset of rules persist during the lifetime of the kernel.\n\nTo see the rough magnitude of checking that the lock validator does, here\u0027s a\nportion of /proc/lockdep_stats, fresh after bootup:\n\n lock-classes:                            694 [max: 2048]\n direct dependencies:                  1598 [max: 8192]\n indirect dependencies:               17896\n all direct dependencies:             16206\n dependency chains:                    1910 [max: 8192]\n in-hardirq chains:                      17\n in-softirq chains:                     105\n in-process chains:                    1065\n stack-trace entries:                 38761 [max: 131072]\n combined max dependencies:         2033928\n hardirq-safe locks:                     24\n hardirq-unsafe locks:                  176\n softirq-safe locks:                     53\n softirq-unsafe locks:                  137\n irq-safe locks:                         59\n irq-unsafe locks:                      176\n\nThe lock validator has observed 1598 actual single-thread locking patterns,\nand has validated all possible 2033928 distinct locking scenarios.\n\nMore details about the design of the lock validator can be found in\nDocumentation/lockdep-design.txt, which can also found at:\n\n   http://redhat.com/~mingo/lockdep-patches/lockdep-design.txt\n\n[bunk@stusta.de: cleanups]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
