ANNELMSG_UNLOAD/CHANNELMSG_UNLOAD_RESPONSE are not traced as these are
mostly used on crash.
Vitaly Kuznetsov (16):
hyper-v: trace vmbus_on_msg_dpc()
hyper-v: trace vmbus_on_message()
hyper-v: trace vmbus_onoffer()
hyper-v: trace vmbus_onoffer_rescind()
hyper-v: trace vmbus_onopen_result()
Add tracepoint to vmbus_on_message() which is called when we start
processing a blocking from work context.
