Hi,

Here's v5 of the min-wait patchset. For a full description, see the v2
posting:

https://lore.kernel.org/io-uring/20240215161002.3044270-1-axboe@kernel.dk/

As before, there's a liburing branch with added test cases, it can be
found here:

https://git.kernel.dk/cgit/liburing/log/?h=min-wait

The patches are on top of master with for-6.12/io_uring pulled in.

Changes since v4:
- Use READ/WRITE_ONCE consistently with iowq->hit_timeout
- Unify how io_cqring_timer_wakeup() handles ring types by always using
  wake_up_process().
- Fix race in min timer wakeup with DEFER_TASKRUN
- Don't reset ctx->cq_wait_nr if timeout has been hit
