I try to explain the difference between ubus_notify and ubus_notify_async. They are the synchronized and asynchronized version of notify seperately. If you want to block yourself until get the respone, you should use ubus_notify, otherwise you should use ubus_notify_async.

But I have the same confusion of difference between ubus_notify and ubus_send_event. I have learned the reference code roughly, and can't tell the actual difference.
