__wake_up_locked_key() and __wake_up_sync_key()\n\nThis patchset introduces wakeup hints for some of the most popular (from\nepoll POV) devices, so that epoll code can avoid spurious wakeups on its\nwaiters.\n\nThe problem with epoll is that the callback-based wakeups do not, ATM,\ncarry any information about the events the wakeup is related to. So the\nonly choice epoll has (not being able to call f_op-\u003epoll() from inside the\ncallback), is to add the file* to a ready-list and resolve the real events\nlater on, at epoll_wait() (or its own f_op-\u003epoll()) time. This can cause\nspurious wakeups, since the wake_up() itself might be for an event the\ncaller is not interested into.\n\nThe rate of these spurious wakeup can be pretty high in case of many\nnetwork sockets being monitored.\n\nBy allowing devices to report the events the wakeups refer to (at least\nthe two major classes - POLLIN/POLLOUT), we are able to spare useless\nwakeups by proper handling inside the epoll\u0027s poll callback.\n\nEpoll will have in any case to call f_op-\u003epoll() on the file* later on,\nsince the change to be done in order to have the full event set sent via\nwakeup, is too invasive for the way our f_op-\u003epoll() system works (the\nfull event set is calculated inside the poll function - there are too many\nof them to even start thinking the change - also poll/select would need\nchange too).\n\nEpoll is changed in a way that both devices which send event hints, and\nthe ones that don\u0027t, are correctly handled. The former will gain some\nefficiency though.\n\nAs a general rule for devices, would be to add an event mask by using\nkey-aware wakeup macros, when making up poll wait queues. I tested it\n(together with the epoll\u0027s poll fix patch Andrew has in -mm) and wakeups\nfor the supported devices are correctly filtered.\n\nTest program available here:\n\nhttp://www.xmailserver.org/epoll_test.c\n\nThis patch:\n\nNothing revolutionary here. Just using the available \"key\" that our\nwakeup core already support. The __wake_up_locked_key() was no brainer,\nsince both __wake_up_locked() and __wake_up_locked_key() are thin wrappers\naround __wake_up_common().\n\nThe __wake_up_sync() function had a body, so the choice was between\nborrowing the body for __wake_up_sync_key() and calling it from\n__wake_up_sync(), or make an inline and calling it from both. I chose the\nformer since in most archs it all resolves to \"mov $0, REG; jmp ADDR\".\n\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: William Lee Irwin III \u003cwli@movementarian.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "46e0bb9c12f4bab539736f1714cbf16600f681ec", "tree": "755769f792c6b59eadfdda02b6a64166bf0ca8d8", "parents": [ "ef12fefabf94b6a902ad3abd3eb124b00560c445" ], "author": { "name": "Gautham R Shenoy", "email": "ego@in.ibm.com", "time": "Mon Mar 30 10:25:20 2009 +0530" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Apr 01 17:58:03 2009 +0200" }, "message": "sched: Print sched_group::__cpu_power in sched_domain_debug\n\nImpact: extend debug info /proc/sched_debug\n\nIf the user changes the value of the sched_mc/smt_power_savings sysfs\ntunable, it\u0027ll trigger a rebuilding of the whole sched_domain tree,\nwith the SD_POWERSAVINGS_BALANCE flag set at certain levels.\n\nAs a result, there would be a change in the __cpu_power of sched_groups\nin the sched_domain hierarchy.\n\nPrint the __cpu_power values for each sched_group in sched_domain_debug\nto help verify this change and correlate it with the change in the\nload-balancing behavior.\n\nSigned-off-by: Gautham R Shenoy \u003cego@in.ibm.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c20090330045520.2869.24777.stgit@sofia.in.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "ef12fefabf94b6a902ad3abd3eb124b00560c445", "tree": "07a23161b84b11379691ab36e6c44464d801b9ac", "parents": [ "c5f8d99585d7b5b7e857fabf8aefd0174903a98c" ], "author": { "name": "Bharata B Rao", "email": "bharata@linux.vnet.ibm.com", "time": "Tue Mar 31 10:02:22 2009 +0530" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Apr 01 16:49:38 2009 +0200" }, "message": "cpuacct: add per-cgroup utime/stime statistics\n\nAdd per-cgroup cpuacct controller statistics like the system and user\ntime consumed by the group of tasks.\n\nChangelog:\n\nv7\n- Changed the name of the statistic from utime to user and from stime to\n system so that in future we could easily add other statistics like irq,\n softirq, steal times etc easily.\n\nv6\n- Fixed a bug in the error path of cpuacct_create() (pointed by Li Zefan).\n\nv5\n- In cpuacct_stats_show(), use cputime64_to_clock_t() since we are\n operating on a 64bit variable here.\n\nv4\n- Remove comments in cpuacct_update_stats() which explained why rcu_read_lock()\n was needed (as per Peter Zijlstra\u0027s review comments).\n- Don\u0027t say that percpu_counter_read() is broken in Documentation/cpuacct.txt\n as per KAMEZAWA Hiroyuki\u0027s review comments.\n\nv3\n- Fix a small race in the cpuacct hierarchy walk.\n\nv2\n- stime and utime now exported in clock_t units instead of msecs.\n- Addressed the code review comments from Balbir and Li Zefan.\n- Moved to -tip tree.\n\nv1\n- Moved the stime/utime accounting to cpuacct controller.\n\nEarlier versions\n- http://lkml.org/lkml/2009/2/25/129\n\nSigned-off-by: Bharata B Rao \u003cbharata@linux.vnet.ibm.com\u003e\nSigned-off-by: Balaji Rao \u003cbalajirrao@gmail.com\u003e\nCc: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nReviewed-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nTested-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nLKML-Reference: \u003c20090331043222.GA4093@in.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c5f8d99585d7b5b7e857fabf8aefd0174903a98c", "tree": "504127a7d4b6a0e3aee56d0822e5e8b23f8062d7", "parents": [ "13b8bd0a5713bdf05659019badd7c0407984ece1" ], "author": { "name": "Hidetoshi Seto", "email": "seto.hidetoshi@jp.fujitsu.com", "time": "Tue Mar 31 16:56:03 2009 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Apr 01 16:44:16 2009 +0200" }, "message": "posixtimers, sched: Fix posix clock monotonicity\n\nImpact: Regression fix (against clock_gettime() backwarding bug)\n\nThis patch re-introduces a couple of functions, task_sched_runtime\nand thread_group_sched_runtime, which was once removed at the\ntime of 2.6.28-rc1.\n\nThese functions protect the sampling of thread/process clock with\nrq lock.

So on the next timer tick, we will enter\ntrigger_load_balance() which will always reschedule() the\nrebalacing softirq:\n\nif (time_after_eq(jiffies, rq-\u003enext_balance))\n\traise_softirq(SCHED_SOFTIRQ);\n\nSo for each tick, we process this pointless softirq.\n\nThis patch fixes it by checking if we are attached to the null\ndomain before raising the softirq, another possible fix would be\nto set the maximal possible JIFFIES value to rq-\u003enext_balance if\nwe are attached to the NULL domain.\n\nv2: build fix on UP\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLKML-Reference: \u003c49af242d.1c07d00a.32d5.ffffc019@mx.google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "28b1bd1cbc33cae95a309691d814399a69cf3070", "tree": "6474d10332662f5302be0df8527c9e9e31e32a95", "parents": [ "2602c3ba4508f528db024c1d209256513ea05de6", "1075414b06109a99b0e87601e84c74a95bd45681" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Mar 04 18:49:19 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Mar 04 18:49:19 2009 +0100" }, "message": "Merge branch \u0027core/locking\u0027 into tracing/ftrace\n" }, { "commit": "a1be621dfacbef0fd374d8acd553d71e07bf29ac", "tree": "32b0355454b43b1098b5e01dd699fd7281abf781", "parents": [ "3612fdf780e28b10323dd12d2b0f306c7ada4d4c", "fec6c6fec3e20637bee5d276fb61dd8b49a3f9cc" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Mar 04 11:14:47 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Mar 04 11:14:47 2009 +0100" }, "message": "Merge branch \u0027tracing/ftrace\u0027; commit \u0027v2.6.29-rc7\u0027 into tracing/core\n" }, { "commit": "b67802ea8061393f7bd2d4db934646e76096027c", "tree": "f2caeed0a8c1f5564e12d63d8c50a89bd3cd6b27", "parents": [ "72fd455ba54b5a02b9c74221b9ded8b1845b464a" ], "author": { "name": "Wang Chen", "email": "wangchen@cn.fujitsu.com", "time": "Mon Mar 02 13:55:26 2009 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 12:02:53 2009 +0100" }, "message": "sched: kill unused parameter of pick_next_task()\n\nImpact: micro-optimization\n\nParameter \"prev\" is not used really.\n\nSigned-off-by: Wang Chen \u003cwangchen@cn.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5512b3ece0cbb5024b83099963222700aa45f59e", "tree": "24d60f354652f8b9ed5b0820aeb9da6add7be493", "parents": [ "c40c6f85a7594ad842233885386a0ca4cd40eafe", "8325d9c09dedf45476f4d6261d1b6a72e4a7453f", "54e991242850edc8c53f71fa5aa3ba7a93ce38f5", "778ef1e6cbb049c9bcbf405936ee6f2b6e451892" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 12:02:36 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 02 12:02:36 2009 +0100" }, "message": "Merge branches \u0027sched/clock\u0027, \u0027sched/urgent\u0027 and \u0027linus\u0027 into sched/core\n" }, { "commit": "54e991242850edc8c53f71fa5aa3ba7a93ce38f5", "tree": "7f136214aab690a8ee4a294ca9c1a7e01de0dc49", "parents": [ "cac64d00c256e65776d575e82aaf540632b66178" ], "author": { "name": "Dhaval Giani", "email": "dhaval@linux.vnet.ibm.com", "time": "Fri Feb 27 15:13:54 2009 +0530" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Feb 27 11:11:53 2009 +0100" }, "message": "sched: don\u0027t allow setuid to succeed if the user does not have rt bandwidth\n\nImpact: fix hung task with certain (non-default) rt-limit settings\n\nCorey Hickey reported that on using setuid to change the uid of a\nrt process, the process would be unkillable and not be running.\nThis is because there was no rt runtime for that user group.

\u003e/sys/kernel/uids/1000/cpu_rt_runtime\n\u003e\n\u003e Seems like every value I try to echo into the /sys files returns EINVAL.\n\nFor UID grouping we initialize the root group with infinite bandwidth\nwhich by default is actually more than the global limit, therefore the\nbandwidth check always fails.\n\nBecause the root group is a phantom group (for UID grouping) we cannot\nruntime adjust it, therefore we let it reflect the global bandwidth\nsettings.\n\nReported-by: Mark Glines \u003cmark@glines.org\u003e\nSigned-off-by: Peter Zijlstra

"message": "mutex: implement adaptive spinning\n\nChange mutex contention behaviour such that it will sometimes busy wait on\nacquisition - moving its behaviour closer to that of spinlocks.\n\nThis concept got ported to mainline from the -rt tree, where it was originally\nimplemented for rtmutexes by Steven Rostedt, based on work by Gregory Haskins.\n\nTesting with Ingo\u0027s test-mutex application (http://lkml.org/lkml/2006/1/8/50)\ngave a 345% boost for VFS scalability on my testbox:\n\n # ./test-mutex-shm V 16 10 | grep \"^avg ops\"\n avg ops/sec: 296604\n\n # ./test-mutex-shm V 16 10 | grep \"^avg ops\"\n avg ops/sec: 85870\n\nThe key criteria for the busy wait is that the lock owner has to be running on\na (different) cpu. The idea is that as long as the owner is running, there is a\nfair chance it\u0027ll release the lock soon, and thus we\u0027ll be better off spinning\ninstead of blocking/scheduling.\n\nSince regular mutexes (as opposed to rtmutexes) do not atomically track the\nowner, we add the owner in a non-atomic fashion and deal with the races in\nthe slowpath.\n\nFurthermore, to ease the testing of the performance impact of this new code,\nthere is means to disable this behaviour runtime (without having to reboot\nthe system), when scheduler debugging is enabled (CONFIG_SCHED_DEBUG\u003dy),\nby issuing the following command:\n\n # echo NO_OWNER_SPIN \u003e /debug/sched_features\n\nThis command re-enables spinning again (this is also the default):\n\n # echo OWNER_SPIN \u003e /debug/sched_features\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "41719b03091911028116155deddc5eedf8c45e37", "tree": "20a699807d78bc0af86b19443dc751415c0cc6f7", "parents": [ "93d81d1aca26e64a75d06a85f7e128b5f49053e7" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jan 14 15:36:26 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 14 18:09:00 2009 +0100" }, "message": "mutex: preemption fixes\n\nThe problem is that dropping the spinlock right before schedule is a voluntary\npreemption point and can cause a schedule, right after which we schedule again.\n\nFix this inefficiency by keeping preemption disabled until we schedule, do this\nby explicity disabling preemption and providing a schedule() variant that\nassumes preemption is already disabled.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "398a153b16b09a68739928d4502455db9725ac86", "tree": "3a584f77d92c49ac8e5a047fd120607c3b5f9727", "parents": [ "b07430ac37103218b5c1e542490a1b98e6deb3d6" ], "author": { "name": "Gregory Haskins", "email": "ghaskins@novell.com", "time": "Wed Jan 14 09:10:04 2009 -0500" }, "committer": { "name": "Gregory Haskins", "email": "ghaskins@novell.com", "time": "Wed Jan 14 09:10:04 2009 -0500" }, "message": "sched: fix build error in kernel/sched_rt.c when RT_GROUP_SCHED \u0026\u0026 !SMP\n\nIngo found a build error in the scheduler when RT_GROUP_SCHED was\nenabled, but SMP was not.
