[GIT PULL] io_uring fixes for 6.13-rc4

[Jens Axboe]

Hi Linus,

Fixes for io_uring that should go into the 6.13-rc4 kernel release. This
pull request contains:

- Fix for a file ref leak for registered ring fds

- Turn the ->timeout_lock into a raw spinlock, as it nests under the
  io-wq lock which is a raw spinlock as it's called from the scheduler
  side

- Limit ring resizing to DEFER_TASKRUN for now. We will broaden this in
  the future, but for now, ensure that it's only feasible on rings with
  a single user

- Add sanity check for io-wq enqueuing

Please pull!
