    Pull io_uring fixes from Jens Axboe:

     - A fix for a missing URING_CMD128 opcode check, fixing an issue with
       the SQE mixed mode support introduced in 6.19. Merged late due to
       having multiple dependencies

     - Add sqe->cmd size checking for big SQEs, similar to what we have for
       normal sized SQEs

     - Fix a race condition in zcrx, that leads to a double free
