Dan,

Rolling the changes you have indicated is not the issue; this can trivially be done.
My contention is that it is not needed given that the underlying function is already
doing that. Look at the function  vmbus_recvpacket_raw() in drivers/hv/channel.c.

I'm confused.

There is no mention of ->offset8 in vmbus_recvpacket_raw().

It's a good idea to add a check there but the lower levels don't know
about the sizeof(synth_kbd_protocol_response) so we would still need
something like my check.
