[GIT PULL] io_uring fixes for 6.16-rc2

[Jens Axboe]

Hi Linus,

A few fixes for io_uring that should go into this release. This pull
request contains:

- Fix for a race between SQPOLL exit and fdinfo reading. It's slim and I
  was only able to reproduce this with an artificial delay in the
  kernel. Followup sparse fix as well to unify the access to ->thread.

- Fix for multiple buffer peeking, avoiding truncation if possible.

- Run local task_work for IOPOLL reaping when the ring is exiting. This
  currently isn't done due to an assumption that polled IO will never
  need task_work, but a fix on the block side is going to change that.

Please pull!
