Hi Linus, 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. Please pull!
