Sorry about that. I am pretty sure I built (with this patch) both vmbus and the util drivers.
This function is  a private function for the vmbus driver and in fact I went back and rebuilt the
drivers in the hv directory without any problem (with this patch applied) in the same tree where
I developed these patches (linux-next tree dated October 2, 2012). Specifically, what was
the build problem you ran into.

K. Y
