I don't understand this part. You add:

    io_uring_register_busy_poll_timeout
    io_uring_unregister_busy_poll_timeout

in the LIBURING_2.3 section.

What are they? I don't find their declaration and definition.

How do they differ from:

    io_uring_napi_register_busy_poll_timeout
    io_uring_napi_unregister_busy_poll_timeout

that you add in the LIBURING_2.4 section?
