# commit 25e73aadf297d78cf528841795cd37bad8320642
# Merge: effaf90137e3 44d282796f81
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'io_uring-5.5-2020-01-16' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes form Jens Axboe:
#     
#      - Ensure ->result is always set when IO is retried (Bijan)
#     
#      - In conjunction with the above, fix a regression in polled IO issue
#        when retried (me/Bijan)
#     
#      - Don't setup async context for read/write fixed, otherwise we may
#        wrongly map the iovec on retry (me)
#     
#      - Cancel io-wq work if we fail getting mm reference (me)
#     
#      - Ensure dependent work is always initialized correctly (me)
#     
#      - Only allow original task to submit IO, don't allow it from a passed
#        ring fd (me)
#     
#     * tag 'io_uring-5.5-2020-01-16' of git://git.kernel.dk/linux-block:
#       io_uring: only allow submit from owning task
#       io_uring: ensure workqueue offload grabs ring mutex for poll list
#       io_uring: clear req->result always before issuing a read/write request
#       io_uring: be consistent in assigning next work from handler
#       io-wq: cancel work if we fail getting a mm reference
#       io_uring: don't setup async context for read/write fixed
