# Merge: db5481e705e2 7316b49c2a11
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Mon Apr 1 08:28:36 2019 -0700

#     Merge branch 'work.aio' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
#     
#     Pull aio race fixes and cleanups from Al Viro.
#     
#     The aio code had more issues with error handling and races with the aio
#     completing at just the right (wrong) time along with freeing the file
#     descriptor when another thread closes the file.
#     
#     Just a couple of these commits are the actual fixes: the others are
#     cleanups to either make the fixes simpler, or to make the code legible
#     and understandable enough that we hope there's no more fundamental races
#     hiding.
#     
#     * 'work.aio' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
#       aio: move sanity checks and request allocation to io_submit_one()
#       deal with get_reqs_available() in aio_get_req() itself
#       aio: move dropping ->ki_eventfd into iocb_destroy()
#       make aio_read()/aio_write() return int
#       Fix aio_poll() races
#       aio: store event at final iocb_put()
#       aio: keep io_event in aio_kiocb
#       aio: fold lookup_kiocb() into its sole caller
#       pin iocb through aio.
