Merge tag 'for-5.7/io_uring-2020-03-29' of git://git.kernel.dk/linux-block
Pull io_uring updates from Jens Axboe: "Here are the io_uring changes for this merge window. Light on new features this time around (just splice + buffer selection), lots of cleanups, fixes, and improvements to existing support. In particular, this contains: - Cleanup fixed file update handling for stack fallback (Hillf) - Re-work of how pollable async IO is handled, we no longer require thread offload to handle that. Instead we rely using poll to drive this, with task_work execution. - In conjunction with the above, allow expendable buffer selection, so that poll+recv (for example) no longer has to be a split operation. - Make sure we honor RLIMIT_FSIZE for buffered writes - Add support for splice (Pavel) - Linked work inheritance fixes and optimizations (Pavel) - Async work fixes and cleanups (Pavel) - Improve io-wq locking (Pavel) - Hashed link write improvements (Pavel) - SETUP_IOPOLL|SETUP_SQPOLL improvements (Xiaoguang)" * tag 'for-5.7/io_uring-2020-03-29' of git://git.kernel.dk/linux-block: (54 commits) io_uring: cleanup io_alloc_async_ctx() io_uring: fix missing 'return' in comment io-wq: handle hashed writes in chains io-uring: drop 'free_pfile' in struct io_file_put io-uring: drop completion when removing file io_uring: Fix ->data corruption on re-enqueue io-wq: close cancel gap for hashed linked work io_uring: make spdxcheck.py happy io_uring: honor original task RLIMIT_FSIZE io-wq: hash dependent work io-wq: split hashing and enqueueing io-wq: don't resched if there is no work io-wq: remove duplicated cancel code io_uring: fix truncated async read/readv and write/writev retry io_uring: dual license io_uring.h uapi header io_uring: io_uring_enter(2) don't poll while SETUP_IOPOLL|SETUP_SQPOLL enabled io_uring: Fix unused function warnings io_uring: add end-of-bits marker and build time verify it io_uring: provide means of removing buffers io_uring: add IOSQE_BUFFER_SELECT support for IORING_OP_RECVMSG ...
