      "message": "wait_event_interruptible_locked() interface\n\nNew wait_event_interruptible{,_exclusive}_locked{,_irq} macros added.\nThey work just like versions without _locked* suffix but require the\nwait queue\u0027s lock to be held.  Also __wake_up_locked() is now exported\nas to pair it with the above macros.\n\nThe use case of this new facility is when one uses wait queue\u0027s lock\nto  protect a data structure.  This may be advantageous if the\nstructure needs to be protected by a spinlock anyway.  In particular,\nwith additional spinlock the following code has to be used to wait\nfor a condition:\n\nspin_lock(\u0026data.lock);\n...\nfor (ret \u003d 0; !ret \u0026\u0026 !(condition); ) {\n\tspin_unlock(\u0026data.lock);\n\tret \u003d wait_event_interruptible(data.wqh, (condition));\n\tspin_lock(\u0026data.lock);\n}\n...\nspin_unlock(\u0026data.lock);\n\nThis looks bizarre plus wait_event_interruptible() locks the wait\nqueue\u0027s lock anyway so there is a unlock+lock sequence where it could\nbe avoided.\n\nTo avoid those problems and benefit from wait queue\u0027s lock, a code\nsimilar to the following should be used:\n\n/* Waiting */\nspin_lock(\u0026data.wqh.lock);\n...\nret \u003d wait_event_interruptible_locked(data.wqh, (condition));\n...\nspin_unlock(\u0026data.wqh.lock);\n\n/* Waiting exclusively */\nspin_lock(\u0026data.whq.lock);\n...\nret \u003d wait_event_interruptible_exclusive_locked(data.whq, (condition));\n...\nspin_unlock(\u0026data.whq.lock);\n\n/* Waking up */\nspin_lock(\u0026data.wqh.lock);\n...\nwake_up_locked(\u0026data.wqh);\n...\nspin_unlock(\u0026data.wqh.lock);\n\nWhen spin_lock_irq() is used matching versions of macros need to be\nused (*_locked_irq()).\n\nSigned-off-by: Michal Nazarewicz \u003cm.nazarewicz@samsung.com\u003e\nCc: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nCc: Marek Szyprowski \u003cm.szyprowski@samsung.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Takashi Iwai \u003ctiwai@suse.de\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Andreas Herrmann \u003candreas.herrmann3@amd.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

      "message": "epoll keyed wakeups: add __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"

And if\nan aborting waiter is concurrently woken up through the waitqueue, noone\nwill ever wake up the next waiter.\n\nThis has been observed with __wait_on_bit_lock() used by\nlock_page_killable(): the first contender on the queue was aborting when\nthe actual lock holder woke it up concurrently.  The aborted contender\ndidn\u0027t acquire the lock and therefor never did an unlock followed by\nwaking up the next waiter.\n\nAdd abort_exclusive_wait() which removes the process\u0027 wait descriptor from\nthe waitqueue, iff still queued, or wakes up the next waiter otherwise.\nIt does so under the waitqueue lock.  Racing with a wake up means the\naborting process is either already woken (removed from the queue) and will\nwake up the next waiter, or it will remove itself from the queue and the\nconcurrent wake up will apply to the next waiter after it.\n\nUse abort_exclusive_wait() in __wait_event_interruptible_exclusive() and\n__wait_on_bit_lock() when they were interrupted by other means than a wake\nup through the queue.\n\n[akpm@linux-foundation.org: coding-style fixes]\nReported-by: Chris Mason \u003cchris.mason@oracle.com\u003e\nSigned-off-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nMentored-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Chuck Lever \u003ccel@citi.umich.edu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[\"after some testing\"]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
