Merge tag 'io_uring-5.18-2022-04-08' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "A bit bigger than usual post merge window, largely due to a revert and
  a fix of at what point files are assigned for requests.

  The latter fixing a linked request use case where a dependent link can
  rely on what file is assigned consistently.

  Summary:

   - 32-bit compat fix for IORING_REGISTER_IOWQ_AFF (Eugene)

   - File assignment fixes (me)

   - Revert of the NAPI poll addition from this merge window. The author
     isn't available right now to engage on this, so let's revert it and
     we can retry for the 5.19 release (me, Jakub)

   - Fix a timeout removal race (me)

   - File update and SCM fixes (Pavel)"
