I noticed the comment label 'wait_event' was wrong.

sched/wait: Fix the signal handling fix

2015-12-13T22:30:59+00:00

Jan Stancek reported that I wrecked things for him by fixing things for
Vladimir :/

His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which
should not be possible, however my previous patch made this possible by
unconditionally checking signal_pending().

We cannot use current->state as was done previously, because the
instruction after the store to that variable it can be changed.  We must
instead pass the initial state along and use that.

net: Generalise wq_has_sleeper helper

2015-11-30T19:47:33+00:00

The memory barrier in the helper wq_has_sleeper is needed by just
about every user of waitqueue_active.  This patch generalises it
by making it take a wait_queue_head_t directly.  The existing
helper is renamed to skwq_has_sleeper.

2015-11-23T08:37:52+00:00

Kosuku reports that there were a fair number of buggy
waitqueue_active() users and this function deserves a big comment in
order to avoid growing more.

userfaultfd: revert "userfaultfd: waitqueue: add nr wake parameter to __wake_up_locked_key"

2015-09-22T22:09:53+00:00

This reverts commit 51360155eccb907ff8635bd10fc7de876408c2e0 and adapts
fs/userfaultfd.c to use the old version of that function.

It didn't look robust to call __wake_up_common with "nr == 1" when we
absolutely require wakeall semantics, but we've full control of what we
insert in the two waitqueue heads of the blocked userfaults.  No
exclusive waitqueue risks to be inserted into those two waitqueue heads
so we can as well stick to "nr == 1" of the old code and we can rely
purely on the fact no waitqueue inserted in one of the two waitqueue
heads we must enforce as wakeall, has wait->flags WQ_FLAG_EXCLUSIVE set.

userfaultfd: waitqueue: add nr wake parameter to __wake_up_locked_key

2015-09-04T23:54:41+00:00

userfaultfd needs to wake all waitqueues (pass 0 as nr parameter), instead
of the current hardcoded 1 (that would wake just the first waitqueue in
the head list).
