Merge tag 'for-6.12/io_uring-20240913' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe: - NAPI fixes and cleanups (Pavel, Olivier) - Add support for absolute timeouts (Pavel) - Fixes for io-wq/sqpoll affinities (Felix) - Efficiency improvements for dealing with huge pages (Chenliang) - Support for a minwait mode, where the application essentially has two timouts - one smaller one that defines the batch timeout, and the overall large one similar to what we had before. This enables efficient use of batching based on count + timeout, while still working well with periods of less intensive workloads - Use ITER_UBUF for single segment sends - Add support for incremental buffer consumption. Right now each operation will always consume a full buffer. With incremental consumption, a recv/read operation only consumes the part of the buffer that it needs to satisfy the operation - Add support for GCOV for io_uring, to help retain a high coverage of test to code ratio - Fix regression with ocfs2, where an odd -EOPNOTSUPP wasn't correctly converted to a blocking retry - Add support for cloning registered buffers from one ring to another - Misc cleanups (Anuj, me) * tag 'for-6.12/io_uring-20240913' of git://git.kernel.dk/linux: (35 commits) io_uring: add IORING_REGISTER_COPY_BUFFERS method io_uring/register: provide helper to get io_ring_ctx from 'fd' io_uring/rsrc: add reference count to struct io_mapped_ubuf io_uring/rsrc: clear 'slot' entry upfront io_uring/io-wq: inherit cpuset of cgroup in io worker io_uring/io-wq: do not allow pinning outside of cpuset io_uring/rw: drop -EOPNOTSUPP check in __io_complete_rw_common() io_uring/rw: treat -EOPNOTSUPP for IOCB_NOWAIT like -EAGAIN io_uring/sqpoll: do not allow pinning outside of cpuset io_uring/eventfd: move refs to refcount_t io_uring: remove unused rsrc_put_fn io_uring: add new line after variable declaration io_uring: add GCOV_PROFILE_URING Kconfig option io_uring/kbuf: add support for incremental buffer consumption io_uring/kbuf: pass in 'len' argument for buffer commit Revert "io_uring: Require zeroed sqe->len on provided-buffers send" io_uring/kbuf: move io_ring_head_to_buf() to kbuf.h io_uring/kbuf: add io_kbuf_commit() helper io_uring/kbuf: shrink nr_iovs/mode in struct buf_sel_arg io_uring: wire up min batch wake timeout ...
