Merge tag 'io_uring-6.13-20242901' of git://git.kernel.dk/linux

Pull more io_uring updates from Jens Axboe:

 - Remove a leftover struct from when the cqwait registered waiting was
   transitioned to regions.

 - Fix for an issue introduced in this merge window, where nop->fd might
   be used uninitialized. Ensure it's always set.

 - Add capping of the task_work run in local task_work mode, to prevent
   bursty and long chains from adding too much latency.

 - Work around xa_store() leaving ->head non-NULL if it encounters an
   allocation error during storing. Just a debug trigger, and can go
   away once xa_store() behaves in a more expected way for this
   condition. Not a major thing as it basically requires fault injection
   to trigger it.

 - Fix a few mapping corner cases

 - Fix KCSAN complaint on reading the table size post unlock. Again not
   a "real" issue, but it's easy to silence by just keeping the reading
   inside the lock that protects it.
