Merge tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull io_uring updates from Jens Axboe:

- Clean up the IORING_SETUP_R_DISABLED and submitter task checking,
mostly just in preparation for relaxing the locking for SINGLE_ISSUER
in the future.

- Improve IOPOLL by using a doubly linked list to manage completions.

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

Pull more io_uring updates from Jens Axboe:
"Set of fixes/updates for io_uring that should go into this release.

The ublk bits could've gone via either tree - usually I put them in
block, but they got a bit mixed this series with the zero-copy
supported that ended up dipping into both trees.

This contains:

- Fix for sendmsg zc, include in pinned pages accounting like we do
for the other zc types

- Series for ublk fixing request aborting, doing various little
cleanups, fixing some zc issues, and adding queue_rqs support

- Another ublk series doing some code cleanups

- Series cleaning up the io_uring send path, mostly in preparation
for registered buffers

- Series doing little MSG_RING cleanups

- Fix for the newly added zc rx, fixing len being 0 for the last
invocation of the callback

- Add vectored registered buffer support for ublk. With that, then
ublk also supports this feature in the kernel revision where it
could generically introduced for rw/net

- A bunch of selftest additions for ublk. This is the majority of the
diffstat

- Silence a KCSAN data race warning for io-wq

- Various little cleanups and fixes"

io_uring: always do atomic put from iowq

io_uring always switches requests to atomic refcounting for iowq
execution before there is any parallilism by setting REQ_F_REFCOUNT,
and the flag is not cleared until the request completes. That should be
fine as long as the compiler doesn't make up a non existing value for
the flags, however KCSAN still complains when the request owner changes
oter flag bits:

BUG: KCSAN: data-race in io_req_task_cancel / io_wq_free_work
