Merge tag 'for-6.5/io_uring-2023-06-23' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe:
"Nothing major in this release, just a bunch of cleanups and some
optimizations around networking mostly.
- clean up file request flags handling (Christoph)
- clean up request freeing and CQ locking (Pavel)
- support for using pre-registering the io_uring fd at setup time
(Josh)
- Add support for user allocated ring memory, rather than having the
kernel allocate it. Mostly for packing rings into a huge page (me)
- avoid an unnecessary double retry on receive (me)
- maintain ordering for task_work, which also improves performance
(me)
- misc cleanups/fixes (Pavel, me)"
