#     Merge tag 'io_uring-5.9-2020-09-06' of git://git.kernel.dk/linux-block
#     
#     Pull more io_uring fixes from Jens Axboe:
#      "Two followup fixes. One is fixing a regression from this merge window,
#       the other is two commits fixing cancelation of deferred requests.
#     
#       Both have gone through full testing, and both spawned a few new
#       regression test additions to liburing.
#     
#        - Don't play games with const, properly store the output iovec and
#          assign it as needed.
#     
#        - Deferred request cancelation fix (Pavel)"
