Don't let io_uring_wait_cqes() submit IO It's a wait interface, if we let it it also touch the SQ side of things, then it's not possible to use sanely in a situation where someone has a separate thread for completions. Note that this may require application changes, if they are currently relying on io_uring_wait_cqes() on also submitting IO. The risk should be minimal however, since it is a wait-for-completions interface. Signed-off-by: Jens Axboe <axboe@kernel.dk>
