Merge tag 'for-6.7/io_uring-2023-10-30' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe: "This contains the core io_uring updates, of which there are not many, and adds support for using WAITID through io_uring and hence not needing to block on these kinds of events. Outside of that, tweaks to the legacy provided buffer handling and some cleanups related to cancelations for uring_cmd support" * tag 'for-6.7/io_uring-2023-10-30' of git://git.kernel.dk/linux: io_uring/poll: use IOU_F_TWQ_LAZY_WAKE for wakeups io_uring/kbuf: Use slab for struct io_buffer objects io_uring/kbuf: Allow the full buffer id space for provided buffers io_uring/kbuf: Fix check of BID wrapping in provided buffers io_uring/rsrc: cleanup io_pin_pages() io_uring: cancelable uring_cmd io_uring: retain top 8bits of uring_cmd flags for kernel internal use io_uring: add IORING_OP_WAITID support exit: add internal include file with helpers exit: add kernel_waitid_prepare() helper exit: move core of do_wait() into helper exit: abstract out should_wake helper for child_wait_callback() io_uring/rw: add support for IORING_OP_READ_MULTISHOT io_uring/rw: mark readv/writev as vectored in the opcode definition io_uring/rw: split io_read() into a helper
