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"
