io_uring: run task_work on io_uring_register()
Do run task_work before io_uring_register(), that might make a first quiesce round much nicer. We generally do that for any syscall invocation to avoid spurious -EINTR/-ERESTARTSYS, for task_work that we generate. This patch brings io_uring_register() inline with the two other io_uring syscalls. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
