No, you should not develop v2 based on my virtio 1.0 support patchset;
it's in a very rough state, and it will not be applied soon: it's for
v2.3, and v2.2 is not relased yet.

So, I would suggest you (always) to make patches based on the latest
git: rebasing (if necessary) won't be too hard after all, especially
for small patch set.

I'd suggest you to send v2, with all comments addressed. I will try
to find a time reviewing your patches next week, to see what I can
help :)
