We normally disable any commands that aren't specifically poll commands for a ring that is setup for polling, but we do allow buffer provide and remove commands to support buffer selection for polled IO. Once a request is issued, we add it to the poll list to poll for completion. But we should not do that for non-IO commands, as those request complete inline immediately and aren't pollable. If we do, we can leave requests on the iopoll list after they are freed. Fixes: ddf0322d ("io_uring: add IORING_OP_PROVIDE_BUFFERS") Signed-off-by:
