For this use case, we should ensure that just io_uring handles this part. It's already got everything setup for it, and I'd rather avoid having drivers touch any of those parts. Could be done by having an io_uring helper ala: io_uring_cmd_complete_in_task(cmd, handler); which takes care of the nitty gritty details. -- Jens Axboe
