Merge tag 'for-7.3/io_uring-20260819' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull io_uring update from Jens Axboe:
 "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"
