If this is set, io_uring will never use an IPI to deliver a task_work notification. This can be used in the common case where a single task or thread communicates with the ring, and doesn't rely on io_uring_cqe_peek(). This provides a noticeable win in performance, both from eliminating the IPI itself, but also from avoiding interrupting the submitting task unnecessarily.
