Merge tag 'for-5.16/io_uring-2021-10-29' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe: "Light on new features - basically just the hybrid mode support. Outside of that it's just fixes, cleanups, and performance improvements. In detail: - Add ring related information to the fdinfo output (Hao) - Hybrid async mode (Hao) - Support for batched issue on block (me) - sqe error trace improvement (me) - IOPOLL efficiency improvements (Pavel) - submit state cleanups and improvements (Pavel) - Completion side improvements (Pavel) - Drain improvements (Pavel) - Buffer selection cleanups (Pavel) - Fixed file node improvements (Pavel) - io-wq setup cancelation fix (Pavel) - Various other performance improvements and cleanups (Pavel) - Misc fixes (Arnd, Bixuan, Changcheng, Hao, me, Noah)" * tag 'for-5.16/io_uring-2021-10-29' of git://git.kernel.dk/linux-block: (97 commits) io-wq: remove worker to owner tw dependency io_uring: harder fdinfo sq/cq ring iterating io_uring: don't assign write hint in the read path io_uring: clusterise ki_flags access in rw_prep io_uring: kill unused param from io_file_supports_nowait io_uring: clean up timeout async_data allocation io_uring: don't try io-wq polling if not supported io_uring: check if opcode needs poll first on arming io_uring: clean iowq submit work cancellation io_uring: clean io_wq_submit_work()'s main loop io-wq: use helper for worker refcounting io_uring: implement async hybrid mode for pollable requests io_uring: Use ERR_CAST() instead of ERR_PTR(PTR_ERR()) io_uring: split logic of force_nonblock io_uring: warning about unused-but-set parameter io_uring: inform block layer of how many requests we are submitting io_uring: simplify io_file_supports_nowait() io_uring: combine REQ_F_NOWAIT_{READ,WRITE} flags io_uring: arm poll for non-nowait files fs/io_uring: Prioritise checking faster conditions first in io_write ...
