Merge tag 'io_uring-6.14-20250214' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:

 - fixes for a potential data corruption issue with IORING_OP_URING_CMD,
   where not all the SQE data is stable. Will be revisited in the
   future, for now it ends up with just always copying it beyond prep to
   provide the same guarantees as all other opcodes

 - make the waitid opcode setup async data like any other opcodes (no
   real fix here, just a consistency thing)

 - fix for waitid io_tw_state abuse

 - when a buffer group is type is changed, do so by allocating a new
   buffer group entry and discard the old one, rather than migrating
