Merge tag 'io_uring-6.4-2023-06-21' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:
 "A fix for a race condition with poll removal and linked timeouts, and
  then a few followup fixes/tweaks for the msg_control patch from last
  week.

  Not super important, particularly the sparse fixup, as it was broken
  before that recent commit. But let's get it sorted for real for this
  release, rather than just have it broken a bit differently"
