Merge tag 'for-6.14/io_uring-20250119' of git://git.kernel.dk/linux

Pull io_uring updates from Jens Axboe:
 "Not a lot in terms of features this time around, mostly just cleanups
  and code consolidation:

   - Support for PI meta data read/write via io_uring, with NVMe and
     SCSI covered

   - Cleanup the per-op structure caching, making it consistent across
     various command types

   - Consolidate the various user mapped features into a concept called
     regions, making the various users of that consistent

   - Various cleanups and fixes"
