Previously it was singly listed, which meant that to complete request N in the chain 0..N-1 had to have completed first. With a doubly linked list we can complete whatever request completes in that order, rather than need to wait for a consecutive range to be available. This reduces latencies. - Improve the restriction setup and checking. Mostly in preparation for adding further features on top of that. Coming in a separate pull request. - Split out task_work and wait handling into separate files. These are mostly nicely abstracted already, but still remained in the io_uring.c file which is on the larger side. - Use GFP_KERNEL_ACCOUNT in a few more spots, where appropriate. - Ensure even the idle io-wq worker exits if a task no longer has any rings open. - Add support for a non-circular submission queue. By default, the SQ ring keeps moving around, even if only a few entries are used for each submission. This can be wasteful in terms of cachelines. If IORING_SETUP_SQ_REWIND is set for the ring when created, each submission will start at offset 0 instead of where we last left off doing submissions. - Various little cleanups * tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (30 commits) io_uring/kbuf: fix memory leak if io_buffer_add_list fails io_uring: Add SPDX id lines to remaining source files io_uring: allow io-wq workers to exit when unused io_uring/io-wq: add exit-on-idle state io_uring/net: don't continue send bundle if poll was required for retry io_uring/rsrc: use GFP_KERNEL_ACCOUNT consistently io_uring/futex: use GFP_KERNEL_ACCOUNT for futex data allocation io_uring/io-wq: handle !sysctl_hung_task_timeout_secs io_uring: fix bad indentation for setup flags if statement io_uring/rsrc: take unsigned index in io_rsrc_node_lookup() io_uring: introduce non-circular SQ io_uring: split out CQ waiting code into wait.c io_uring: split out task work code into tw.c io_uring/io-wq: don't trigger hung task for syzbot craziness io_uring: add IO_URING_EXIT_WAIT_MAX definition io_uring/sync: validate passed in offset io_uring/eventfd: remove unused ctx->evfd_last_cq_tail member io_uring/timeout: annotate data race in io_flush_timeouts() io_uring/uring_cmd: explicitly disallow cancelations for IOPOLL io_uring: fix IOPOLL with passthrough I/O ... |
