[GIT PULL] Followup io_uring fixes for 6.19-rc1

[Jens Axboe]

Hi Linus,

Followup set of fixes for io_uring for this merge window. These are
either later fixes, or cleanups that don't make sense to defer. This
pull request contains:

- Fix for a recent regression in io-wq worker creation.

- Tracing cleanup

- Use READ_ONCE/WRITE_ONCE consistently for ring mapped kbufs. Mostly
  for documentation purposes, indicating that they are shared with
  userspace.

- Fix for POLL_ADD losing a completion, if the request is updated and
  now is triggerable - eg, if POLLIN is set with the updated, and the
  polled file is readable.

- In conjunction with the above fix, also unify how poll wait queue
  entries are deleted with the head update. We had 3 different spots
  doing both the list deletion and head write, with one of them nicely
  documented. Abstract that into a helper and use it consistently.

- Small series from Joanne fixing an issue with buffer cloning, and
  cleaning up the arg validation.

Please pull!
