Merge tag 'for-5.17/io_uring-2022-01-11' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe:
- Support for prioritized work completions (Hao)
- Simplification of reissue (Pavel)
- Add support for CQE skip (Pavel)
- Memory leak fix going to 5.15-stable (Pavel)
- Re-write of internal poll. This both cleans up that code, and gets us
ready to fix the POLLFREE issue (Pavel)
- Various cleanups (GuoYong, Pavel, Hao)
