Merge tag 'io_uring-6.6-2023-09-08' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:
 "A few fixes that should go into the 6.6-rc merge window:

   - Fix for a regression this merge window caused by the SQPOLL
     affinity patch, where we can race with SQPOLL thread shutdown and
     cause an oops when trying to set affinity (Gabriel)

   - Fix for a regression this merge window where fdinfo reading with
     for a ring setup with IORING_SETUP_NO_SQARRAY will attempt to
     deference the non-existing SQ ring array (me)

   - Add the patch that allows more finegrained control over who can use
     io_uring (Matteo)

   - Locking fix for a regression added this merge window for IOPOLL
     overflow (Pavel)

   - IOPOLL fix for stable, breaking our loop if helper threads are
     exiting (Pavel)

  Also had a fix for unreaped iopoll requests from io-wq from Ming, but
  we found an issue with that and hence it got reverted. Will get this
  sorted for a future rc"
