Another question for KY:
In my testing, while busy-looping in vmbus_wait_for_unload, I see a few
"message_type==1, hdr->msgtype==2" in the hv_context.synic_message_page
of the cpu which will deliver CHANNELMSG_UNLOAD_RESPONSE.
These values are not listed in their enum lists. Any idea what these
values mean?
