Merge tag 'for-6.15/io_uring-20250322' of git://git.kernel.dk/linux

Pull io_uring updates from Jens Axboe:
"This is the first of the io_uring pull requests for the 6.15 merge
window, there will be others once the net tree has gone in. This
contains:

- Cleanup and unification of cancelation handling across various
request types.

- Improvement for bundles, supporting them both for incrementally
consumed buffers, and for non-multishot requests.

- Enable toggling of using iowait while waiting on io_uring events or
not. Unfortunately this is still tied with CPU frequency boosting
on short waits, as the scheduler side has not been very receptive
to splitting the (useless) iowait stat from the cpufreq implied
boost.

- Add support for kbuf nodes, enabling zero-copy support for the ublk
block driver.

- Various cleanups for resource node handling.

- Series greatly cleaning up the legacy provided (non-ring based)
buffers. For years, we've been pushing the ring provided buffers as
the way to go, and that is what people have been using. Reduce the
complexity and code associated with legacy provided buffers.

- Series cleaning up the compat handling.

- Series improving and cleaning up the recvmsg/sendmsg iovec and msg
handling.

- Series of cleanups for io-wq.

- Start adding a bunch of selftests. The liburing repository
generally carries feature and regression tests for everything, but
at least for ublk initially, we'll try and go the route of having
it in selftests as well. We'll see how this goes, might decide to
migrate more tests this way in the future.

- Various little cleanups and fixes"

selftests: ublk: add kernel selftests for ublk

Both ublk driver and userspace heavily depends on io_uring subsystem,
and tools/testing/selftests/ should be the best place for holding this

Add basic read/write IO test over this ublk null disk, and make sure ublk
working.

More tests will be added.
