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.

Presently this requires\na global kernel TLB flush, which on most architectures is a broadcast IPI\nto all CPUs to flush the cache. This is all done under a global lock. As\nthe number of CPUs increases, so will the number of vunmaps a scaled\nworkload will want to perform, and so will the cost of a global TLB flush.\n This gives terrible quadratic scalability characteristics.\n\nAnother problem is that the entire vmap subsystem works under a single\nlock. It is a rwlock, but it is actually taken for write in all the fast\npaths, and the read locking would likely never be run concurrently anyway,\nso it\u0027s just pointless.\n\nThis is a rewrite of vmap subsystem to solve those problems. The existing\nvmalloc API is implemented on top of the rewritten subsystem.\n\nThe TLB flushing problem is solved by using lazy TLB unmapping. vmap\naddresses do not have to be flushed immediately when they are vunmapped,\nbecause the kernel will not reuse them again (would be a use-after-free)\nuntil they are reallocated. So the addresses aren\u0027t allocated again until\na subsequent TLB flush. A single TLB flush then can flush multiple\nvunmaps from each CPU.\n\nXEN and PAT and such do not like deferred TLB flushing because they can\u0027t\nalways handle multiple aliasing virtual addresses to a physical address.\nThey now call vm_unmap_aliases() in order to flush any deferred mappings.\nThat call is very expensive (well, actually not a lot more expensive than\na single vunmap under the old scheme), however it should be OK if not\ncalled too often.\n\nThe virtual memory extent information is stored in an rbtree rather than a\nlinked list to improve the algorithmic scalability.\n\nThere is a per-CPU allocator for small vmaps, which amortizes or avoids\nglobal locking.\n\nTo use the per-CPU interface, the vm_map_ram / vm_unmap_ram interfaces\nmust be used in place of vmap and vunmap. Vmalloc does not use these\ninterfaces at the moment, so it will not be quite so scalable (although it\nwill use lazy TLB flushing).\n\nAs a quick test of performance, I ran a test that loops in the kernel,\nlinearly mapping then touching then unmapping 4 pages. Different numbers\nof tests were run in parallel on an 4 core, 2 socket opteron. Results are\nin nanoseconds per map+touch+unmap.\n\nthreads vanilla vmap rewrite\n1 14700 2900\n2 33600 3000\n4 49500 2800\n8 70631 2900\n\nSo with a 8 cores, the rewritten version is already 25x faster.\n\nIn a slightly more realistic test (although with an older and less\nscalable version of the patch), I ripped the not-very-good vunmap batching\ncode out of XFS, and implemented the large buffer mapping with vm_map_ram\nand vm_unmap_ram... along with a couple of other tricks, I was able to\nspeed up a large directory workload by 20x on a 64 CPU system. I believe\nvmap/vunmap is actually sped up a lot more than 20x on such a system, but\nI\u0027m running into other locks now. vmap is pretty well blown off the\nprofiles.\n\nBefore:\n1352059 total 0.1401\n798784 _write_lock 8320.6667 \u003c- vmlist_lock\n529313 default_idle 1181.5022\n 15242 smp_call_function 15.8771 \u003c- vmap tlb flushing\n 2472 __get_vm_area_node 1.9312 \u003c- vmap\n 1762 remove_vm_area 4.5885 \u003c- vunmap\n 316 map_vm_area 0.2297 \u003c- vmap\n 312 kfree 0.1950\n 300 _spin_lock 3.1250\n 252 sn_send_IPI_phys 0.4375 \u003c- tlb flushing\n 238 vmap 0.8264 \u003c- vmap\n 216 find_lock_page 0.5192\n 196 find_next_bit 0.3603\n 136 sn2_send_IPI 0.2024\n 130 pio_phys_write_mmr 2.0312\n 118 unmap_kernel_range 0.1229\n\nAfter:\n 78406 total 0.0081\n 40053 default_idle 89.4040\n 33576 ia64_spinlock_contention 349.7500\n 1650 _spin_lock 17.1875\n 319 __reg_op 0.5538\n 281 _atomic_dec_and_lock 1.0977\n 153 mutex_unlock 1.5938\n 123 iget_locked 0.1671\n 117 xfs_dir_lookup 0.1662\n 117 dput 0.1406\n 114 xfs_iget_core 0.0268\n 92 xfs_da_hashname 0.1917\n 75 d_alloc 0.0670\n 68 vmap_page_range 0.0462 \u003c- vmap\n 58 kmem_cache_alloc 0.0604\n 57 memset 0.0540\n 52 rb_next 0.1625\n 50 __copy_user 0.0208\n 49 bitmap_find_free_region 0.2188 \u003c- vmap\n 46 ia64_sn_udelay 0.1106\n 45 find_inode_fast 0.1406\n 42 memcmp 0.2188\n 42 finish_task_switch 0.1094\n 42 __d_lookup 0.0410\n 40 radix_tree_lookup_slot 0.1250\n 37 _spin_unlock_irqrestore 0.3854\n 36 xfs_bmapi 0.0050\n 36 kmem_cache_free 0.0256\n 35 xfs_vn_getattr 0.0322\n 34 radix_tree_lookup 0.1062\n 33 __link_path_walk 0.0035\n 31 xfs_da_do_buf 0.0091\n 30 _xfs_buf_find 0.0204\n 28 find_get_page 0.0875\n 27 xfs_iread 0.0241\n 27 __strncpy_from_user 0.2812\n 26 _xfs_buf_initialize 0.0406\n 24 _xfs_buf_lookup_pages 0.0179\n 24 vunmap_page_range 0.0250 \u003c- vunmap\n 23 find_lock_page 0.0799\n 22 vm_map_ram 0.0087 \u003c- vmap\n 20 kfree 0.0125\n 19 put_page 0.0330\n 18 __kmalloc 0.0176\n 17 xfs_da_node_lookup_int 0.0086\n 17 _read_lock 0.0885\n 17 page_waitqueue 0.0664\n\nvmap has gone from being the top 5 on the profiles and flushing the crap\nout of all TLBs, to using less than 1% of kernel time.\n\n[akpm@linux-foundation.org: cleanups, section fix]\n[akpm@linux-foundation.org: fix build on alpha]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nCc: Krzysztof Helt \u003ckrzysztof.h1@poczta.fm\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "73b4a24f5ff09389ba6277c53a266b142f655ed2", "tree": "81c6d539589c8b2414b4e8b99814b1f18769a37e", "parents": [ "1b821bfb034c5db5af62b463e3001243905179ba" ], "author": { "name": "Adrian Bunk", "email": "bunk@kernel.org", "time": "Thu Oct 16 23:29:21 2008 +0300" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 16 13:35:34 2008 -0700" }, "message": "init/do_mounts_md.c must #include \u003clinux/delay.h\u003e\n\nThis patch fixes the following compile error caused by commit\n589f800bb12c5cd6c9167bbf9bf3cb70cd8e422c (\"fastboot: make the raid\nautodetect code wait for all devices to init\"):\n\n CC init/do_mounts_md.o\n init/do_mounts_md.c: In function \u0027autodetect_raid\u0027:\n init/do_mounts_md.c:285: error: implicit declaration of function \u0027msleep\u0027\n make[2]: *** [init/do_mounts_md.o] Error 1\n\nSigned-off-by: Adrian Bunk \u003cbunk@kernel.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ebf3f09c634906d371f2bfd71b41c7e0c52efe7e", "tree": "4205040f47fba2675dc4c6b1407d15c9d6f8b355", "parents": [ "d8273674721faaf84bec2190c0c7a82972b37f73" ], "author": { "name": "Thomas Petazzoni", "email": "thomas.petazzoni@free-electrons.com", "time": "Wed Oct 15 22:05:12 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 16 11:21:51 2008 -0700" }, "message": "Configure out AIO support\n\nThis patchs adds the CONFIG_AIO option which allows to remove support\nfor asynchronous I/O operations, that are not necessarly used by\napplications, particularly on embedded devices.

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] | [%]

One problem spot are\nkernel timers, where the detection of the problem often happens in interrupt\ncontext and usually causes the machine to panic.\n\nWhile working on a timer related bug report I had to hack specialized code\ninto the timer subsystem to get a reasonable hint for the root cause. This\ndebug hack was fine for temporary use, but far from a mergeable solution due\nto the intrusiveness into the timer code.\n\nThe code further lacked the ability to detect and report the root cause\ninstantly and keep the system operational.\n\nKeeping the system operational is important to get hold of the debug\ninformation without special debugging aids like serial consoles and special\nknowledge of the bug reporter.\n\nThe problems described above are not restricted to timers, but timers tend to\nexpose it usually in a full system crash. Other objects are less explosive,\nbut the symptoms caused by such mistakes can be even harder to debug.\n\nInstead of creating specialized debugging code for the timer subsystem a\ngeneric infrastructure is created which allows developers to verify their code\nand provides an easy to enable debug facility for users in case of trouble.\n\nThe debugobjects core code keeps track of operations on static and dynamic\nobjects by inserting them into a hashed list and sanity checking them on\nobject operations and provides additional checks whenever kernel memory is\nfreed.\n\nThe tracked object operations are:\n- initializing an object\n- adding an object to a subsystem list\n- deleting an object from a subsystem list\n\nEach operation is sanity checked before the operation is executed and the\nsubsystem specific code can provide a fixup function which allows to prevent\nthe damage of the operation. When the sanity check triggers a warning message\nand a stack trace is printed.\n\nThe list of operations can be extended if the need arises. For now it\u0027s\nlimited to the requirements of the first user (timers).\n\nThe core code enqueues the objects into hash buckets. The hash index is\ngenerated from the address of the object to simplify the lookup for the check\non kfree/vfree. Each bucket has it\u0027s own spinlock to avoid contention on a\nglobal lock.\n\nThe debug code can be compiled in without being active. The runtime overhead\nis minimal and could be optimized by asm alternatives. A kernel command line\noption enables the debugging code.\n\nThanks to Ingo Molnar for review, suggestions and cleanup patches.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5cd204550b1a006f2b0c986b0e0f53220ebfd391", "tree": "ee0f5e042072d4d2f4a3c6cd6e3a8b60676868ae", "parents": [ "cb41d6d068716b2b3666925da34d3d7e658bf4f3" ], "author": { "name": "Pavel Emelyanov", "email": "xemul@openvz.org", "time": "Wed Apr 30 00:54:24 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:48 2008 -0700" }, "message": "Deprecate find_task_by_pid()\n\nThere are some places that are known to operate on tasks\u0027\nglobal pids only:\n\n* the rest_init() call (called on boot)\n* the kgdb\u0027s getthread\n* the create_kthread() (since the kthread is run in init ns)\n\nSo use the find_task_by_pid_ns(..., \u0026init_pid_ns) there\nand schedule the find_task_by_pid for removal.\n\n[sukadev@us.ibm.com: Fix warning in kernel/pid.c]\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: \"Eric W.
