That means we mark the interrupt disabled, but\nleave the hardware unmasked. That\u0027s an optimization because we avoid\nthe hardware access for the common case where no interrupt happens\nafter we marked it disabled. If an interrupt happens, then the\ninterrupt flow handler masks the line at the hardware level and marks\nit pending.\n\nSuspend makes use of this delayed disable as it \"disables\" all\ninterrupts when preparing the suspend transition. Right before the\nsystem goes into hardware suspend state it checks whether one of the\ninterrupts which is marked as a wakeup interrupt came in after\ndisabling it.\n\nMost interrupt chips have a separate register which selects the\ninterrupts which can wake up the system from suspend, so we don\u0027t have\nto mask any on the non wakeup interrupts.\n\nBut now we have to deal with brilliant designed hardware which lacks\nsuch a wakeup configuration facility. For such hardware it\u0027s necessary\nto mask all non wakeup interrupts before going into suspend in order\nto avoid the wakeup from random interrupts.\n\nRather than working around this in the affected interrupt chip\nimplementations we can solve this elegant in the core code itself.\n\nAdd a flag IRQCHIP_MASK_ON_SUSPEND which can be set by the irq chip\nimplementation to indicate, that the interrupts which are not selected\nas wakeup sources must be masked in the suspend path.

This means that when we\nexit, we want all references to the rpc_task to be gone, and we want\nany dentry references etc. held by that task to be released.\n\nFor this reason these functions call __rpc_wait_for_completion_task(),\nfollowed by rpc_put_task() in the expectation that the latter will be\nreleasing the last reference to the rpc_task, and thus ensuring that the\ncallback_ops-\u003erpc_release() has been called synchronously.\n\nThis patch fixes a race which exists due to the fact that\nrpciod calls rpc_complete_task() (in order to wake up the callers of\n__rpc_wait_for_completion_task()) and then subsequently calls\nrpc_put_task() without ensuring that these two steps are done atomically.\n\nIn order to avoid adding new spin locks, the patch uses the existing\nwaitqueue spin lock to order the rpc_task reference count releases between\nthe waiting process and rpciod.\nThe common case where nobody is waiting for completion is optimised for by\nchecking if the RPC_TASK_ASYNC flag is cleared and/or if the rpc_task\nreference count is 1: in those cases we drop trying to grab the spin lock,\nand immediately free up the rpc_task.\n\nThose few processes that need to put the rpc_task from inside an\nasynchronous context and that do not care about ordering are given a new\nhelper: rpc_put_task_async().\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "8fe8f545c6d753ead15e1f4919d39e8f9bb49629", "tree": "b188ce42c3b18f481e6f727004499171aa5462c1", "parents": [ "a5abba989deceb731047425812d268daf7536575" ], "author": { "name": "Michel Lespinasse", "email": "walken@google.com", "time": "Sun Mar 06 18:07:50 2011 -0800" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Mar 10 19:56:18 2011 +0100" }, "message": "futex: Update futex_wait_setup comments about locking\n\nReviving a cleanup I had done about a year ago as part of a larger\nfutex_set_wait proposal.

With the patch, the\ntask is throttled and runs as expected.\n\n[ bharata, suggestions on how to pick the rt_se belong to the\n rt_rq and correct cpu ]\n\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nAcked-by: Bharata B Rao \u003cbharata@linux.vnet.ibm.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: stable@kernel.org\nLKML-Reference: \u003c20110303113435.GA2868@balbir.in.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "888a8a3e9d79cbb9d83e53955f684998248580ec", "tree": "3dbf548438c77d89c8696a9a79c4129cdc2f3d3e", "parents": [ "cfff2d909cbdaf8c467bd321aa0502a548ec8f7e", "b06b3d49699a52e8f9ca056c4f96e81b1987d78e" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Mar 04 10:40:22 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Mar 04 10:40:25 2011 +0100" }, "message": "Merge branch \u0027perf/urgent\u0027 into perf/core\n\nMerge reason: Pick up updates before queueing up dependent patches.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2d3a8497f8cc5aca14b722cd37d51f6c15ff9f74", "tree": "2e0013fdc1eec486a425e666a885b04a1c37befb", "parents": [ "255bb490c8c27eed484d538efe6ef6a7473bd3f6" ], "author": { "name": "Tao Ma", "email": "boyu.mt@taobao.com", "time": "Thu Mar 03 10:53:20 2011 -0500" }, "committer": { "name": "Jens Axboe", "email": "jaxboe@fusionio.com", "time": "Thu Mar 03 10:53:20 2011 -0500" }, "message": "blktrace: Remove blk_fill_rwbs_rq.\n\nIf we enable trace events to trace block actions, We use\nblk_fill_rwbs_rq to analyze the corresponding actions\nin request\u0027s cmd_flags, but we only choose the minor 2 bits\nfrom it, so most of other flags(e.g, REQ_SYNC) are missing.\nFor example, with a sync write we get:\nwrite_test-2409 [001] 160.013869: block_rq_insert: 3,64 W 0 () 258135 + \u003d\n8 [write_test]\n\nSince now we have integrated the flags of both bio and request,\nit is safe to pass rq-\u003ecmd_flags directly to blk_fill_rwbs and\nblk_fill_rwbs_rq isn\u0027t needed any more.\n\nWith this patch, after a sync write we get:\nwrite_test-2417 [000] 226.603878: block_rq_insert: 3,64 WS 0 () 258135 +\u003d\n 8 [write_test]\n\nSigned-off-by: Tao Ma \u003cboyu.mt@taobao.com\u003e\nAcked-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "c09d7a3d2e365e11c09b9c6414c17fe55bd32a8e", "tree": "8823dc4ba7ab25af71a0df8187ea800f0123aeff", "parents": [ "0a10247914a5cad3caf7ef8a255c54c4d3ed2062", "4defe682d81a4960b6840ee4ed1a36f9db77c7bd" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Mar 02 16:09:55 2011 +0100" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Mar 03 04:29:25 2011 +0100" }, "message": "Merge branch \u0027/tip/perf/filter\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git into perf/core\n" }, { "commit": "5cd10e7946d28cfc42442fee2e6c757e244d756e", "tree": "3886b72694e0edb7334f9a17ac9325f8b068c6e6", "parents": [ "7fdd7f89006dd5a4c702fa0ce0c272345fa44ae0" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Mar 02 16:58:30 2011 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Mar 02 17:20:00 2011 +0100" }, "message": "hrtimer: Update base[CLOCK_BOOTTIME].offset correctly\n\nWe calculate the current time of each clock base by adding an offset\nto clock_monotonic.
