Subject: Move ep_take_care_of_epollwakeup() to fs/eventpoll.c
X-Git-Tag: v6.4-rc1~167^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=063f3ed9faf38e41449838bb3258a7d00f75c5d1;p=thirdparty%2Flinux.git

Move ep_take_care_of_epollwakeup() to fs/eventpoll.c

This doesn't make any sense to expose to userspace, so it's been moved
to the one user.  This was introduced by commit 95f19f658ce1 ("epoll:
drop EPOLLWAKEUP if PM_SLEEP is disabled").
