charset=UTF-8 Content-Transfer-Encoding: 7bit Hi Linus, Trying to get back to a regular schedule again post the summer break, but alas this PR is later than I like to do them. Still early in the merge window, but I always try to have them out on Sunday/Monday. Anyways, here are the io_uring changes queued for 7.3. On top of the usual cleanups and fixes, the bigger items in here are: - zcrx work, most of it centered around adding dynamic area provisioning, plus a bunch of prep and cleanups leading up to it: scale refilling with large pages, coalesce same-niov RQEs on refill, separate the RQ head/tail cache lines and cache the RQ tail, and rework the area creation locking. - Fix the futex inflight accounting so that only private futex waits are marked inflight, and don't mark wake requests as inflight at all. - Drop the custom iov copy in the buffer select prep and msg header copy paths, using the generic helpers instead. - Fix a folio size overflow in io_vec_fill_bvec(), and account the pages a compound region really uses in the memmap path. - Fix an iovec leak in uring_cmd when the async cmd isn't recycled, skip the blocking task work for io_uring_cmd_issue_blocking(), and don't skip completion for a synchronous multishot cmd - Defer eventfd signaling when queued from a wakeup handler - Fix io-wq worker accounting when canceling creation callbacks - Annotate remote tasks for kcoverage Note: you'll get a trivial merge conflict in include/uapi/linux/io_uring/zcrx.h due to the rename changes that we applied to 7.2 before this API was released, it was in the io_uring-7.2-20260724 pull request I sent you. Please pull!
