Sorry; I didn't intend to belittle your opinions.  Since we want to
push code to drivers/virt/, I figured it would be prudent to get
permission from those folks reported by:

	./scripts/get_maintainer.pl -f drivers/virt/

first.  That was the intent of my original email, and why I chose
the distribution list I did.

I've never done this before, so I spend quite a lot of time groping
around blindly...   ;-(
