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": "a8af78982ff4c0b3731527b0217d286a343a3089", "tree": "10f0ebe13c999dd54efdf79ff606b65e7952b69d", "parents": [ "5f0e3da6e186598bbd2569410ab60fa645ba00c9" ], "author": { "name": "Magnus Damm", "email": "damm@igel.co.jp", "time": "Tue Mar 31 15:23:37 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 01 08:59:16 2009 -0700" }, "message": "pm: rework includes, remove arch ifdefs\n\nMake the following header file changes:\n\n - remove arch ifdefs and asm/suspend.h from linux/suspend.h\n - add asm/suspend.h to disk.c (for arch_prepare_suspend())\n - add linux/io.h to swsusp.c (for ioremap())\n - x86 32/64 bit compile fixes\n\nSigned-off-by: Magnus Damm \u003cdamm@igel.co.jp\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nAcked-by: \"Rafael J.

With this patch update_rlimit_cpu()\nis not really needed, but I don\u0027t think it should be removed.\n\nThe proper fix (I think) is:\n\n\t- set_process_cpu_timer() should just start the cputimer-\u003erunning\n\t logic (it does), no need to change cputime_expires.xxx_exp\n\n\t- posix_cpu_timers_init_group() should set -\u003erunning when needed\n\n\t- fastpath_timer_check() can check -\u003erunning instead of\n\t task_cputime_zero(signal-\u003ecputime_expires)\n\nReported-by: Peter Lojkin \u003cia6432@inbox.ru\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: \u003cstable@kernel.org\u003e [for 2.6.29.x]\nLKML-Reference: \u003c20090323193411.GA17514@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "53da1d9456fe7f87a920a78fdbdcf1225d197cb7", "tree": "eccd5357ceff25a9a07be802ac0161c8c1842e64", "parents": [ "b0dcb4a91ddb79f2e213205cf8d86b467f8559c7" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Mon Mar 23 16:07:24 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 23 09:22:31 2009 -0700" }, "message": "fix ptrace slowness\n\nThis patch fixes bug #12208:\n\n Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id\u003d12208\n Subject : uml is very slow on 2.6.28 host\n\nThis turned out to be not a scheduler regression, but an already\nexisting problem in ptrace being triggered by subtle scheduler\nchanges.\n\nThe problem is this:\n\n - task A is ptracing task B\n - task B stops on a trace event\n - task A is woken up and preempts task B\n - task A calls ptrace on task B, which does ptrace_check_attach()\n - this calls wait_task_inactive(), which sees that task B is still on the runq\n - task A goes to sleep for a jiffy\n - ...\n\nSince UML does lots of the above sequences, those jiffies quickly add\nup to make it slow as hell.\n\nThis patch solves this by not rescheduling in read_unlock() after\nptrace_stop() has woken up the tracer.\n\nThanks to Oleg Nesterov and Ingo Molnar for the feedback.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCC: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "efd247fa34084d9b162f485004ae6d8a04059f0c", "tree": "417dcbe06d5cce1353a4c19cbda480ae67652b5c", "parents": [ "af66df5ecf9c9e2d2ff86e8203510c1c4519d64c", "59fcbddaff6f862cc1584b488866d9c4a5579085" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 23 16:53:20 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 23 16:53:20 2009 +0100" }, "message": "Merge branches \u0027sched/debug\u0027 and \u0027linus\u0027 into sched/core\n" }, { "commit": "b3e3b302cf6dc8d60b67f0e84d1fa5648889c038", "tree": "3f6150291664b4c62e328f6b1dcff79b54db612a", "parents": [ "a6bc3262c561780d2a6587aa3d5715b1e7d8fa13", "59fcbddaff6f862cc1584b488866d9c4a5579085" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 23 10:07:49 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Mar 23 10:07:49 2009 +0100" }, "message": "Merge branches \u0027irq/sparseirq\u0027 and \u0027linus\u0027 into irq/core\n" }, { "commit": "af66df5ecf9c9e2d2ff86e8203510c1c4519d64c", "tree": "c87b608c16911c48a9a55167891489f5714f66c7", "parents": [ "37ba317c9ed19eb126e40bbf563f2711e191a636" ], "author": { "name": "Luis Henriques", "email": "henrix@sapo.pt", "time": "Wed Mar 18 00:04:25 2009 +0000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Mar 18 09:57:26 2009 +0100" }, "message": "sched: jiffies not printed per CPU\n\nThe jiffies value was being printed for each CPU, which does not seem to make\nsense.

This causes acct_timexpd to be\ngreater than the former stime + utime. The subsequent calculation of\n\n\tdtime \u003d cputime_sub(time, tsk-\u003eacct_timexpd);\n\nwill be negative and the division performed by\n\n\tcputime_to_jiffies(dtime)\n\nwill generate an exception since the result won\u0027t fit into a 32 bit\nregister.\n\nIn order to fix this just always disable interrupts while accessing any\nof the accounting values.\n\nReported by: Frans Pop \u003celendil@planet.nl\u003e\nTested by: Frans Pop \u003celendil@planet.nl\u003e\nCc: stable@kernel.org\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5ed0cec0ac5f1b3759bdbe4d9df32ee4ff8afb5a", "tree": "a804da35b296f278865b194661cc6e75bfdaf11f", "parents": [ "7fc07d84108d54c5b94625c0e168f31b2d66976e" ], "author": { "name": "Lai Jiangshan", "email": "laijs@cn.fujitsu.com", "time": "Fri Mar 06 19:40:20 2009 +0800" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Mar 06 12:48:55 2009 +0100" }, "message": "sched: TIF_NEED_RESCHED -\u003e need_reshed() cleanup\n\nImpact: cleanup\n\nUse test_tsk_need_resched(), set_tsk_need_resched(), need_resched()\ninstead of using TIF_NEED_RESCHED.\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c49B10BA4.9070209@cn.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "7fc07d84108d54c5b94625c0e168f31b2d66976e" }
