Merge tag 'io_uring-6.16-20250614' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:

 - 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.
