The trick here is to consider io_uring\nregistered files for cycle detection but not actually putting them down.\nBecause io_uring can't register other ring instances, this will remove\nall refs to the ring file triggering the ->release path and clean up\nwith io_ring_ctx_free().\n\n[axboe: add kerneldoc comment to skb, fold in skb leak fix]"
