#     Merge tag 'io_uring-5.5-2020-01-26' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes from Jens Axboe:
#      "Fix for two regressions in this cycle, both reported by the postgresql
#       use case.
#     
#       One removes the added restriction on who can submit IO, making it
#       possible for rings shared across forks to do so. The other fixes an
#       issue for the same kind of use case, where one exiting process would
#       cancel all IO"
#     
#     * tag 'io_uring-5.5-2020-01-26' of git://git.kernel.dk/linux-block:
#       io_uring: don't cancel all work on process exit
#       Revert "io_uring: only allow submit from owning task"
