I don't want to make this change now. Additionally, it's never going to be possible to support polled IO mixed with non-polled IO on an io_uring instance, as that makes the wait part of IO impossible to support without adding tracking of requests. As we can never mix them, it doesn't make a lot of sense to request RWF_HIPRI for polled IO. -- Jens Axboe
