#     Merge tag 'io_uring-5.15-2021-09-25' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes from Jens Axboe:
#      "This one looks a bit bigger than it is, but that's mainly because 2/3
#       of it is enabling IORING_OP_CLOSE to close direct file descriptors.
#     
#       We've had a few folks using them and finding it confusing that the way
#       to close them is through using -1 for file update, this just brings
#       API symmetry for direct descriptors. Hence I think we should just do
#       this now and have a better API for 5.15 release. There's some room for
#       de-duplicating the close code, but we're leaving that for the next
#       merge window.
#     
#       Outside of that, just small fixes:
#     
#        - Poll race fixes (Hao)
#     
#        - io-wq core dump exit fix (me)
#     
#        - Reschedule around potentially intensive tctx and buffer iterators
#          on teardown (me)
#     
#        - Fix for always ending up punting files update to io-wq (me)
#     
#        - Put the provided buffer meta data under memcg accounting (me)
#     
#        - Tweak for io_write(), removing dead code that was added with the
#          iterator changes in this release (Pavel)"
