Hi Yinghai,

Attached is my suggested update to your patch. It allows a SCI to be
sent to any object, and therefore can be used for testing the global
notify handler. Some drivers such as dock.c only register their handler
to the global notify handler. I also made a few minor changes. I have
been testing with this update and it is working fine. I like this
feature, so I hope we can make progress with this update.

Thanks,
