Jeromé, Can you please apply the following patch: http://pastebin.com/jVTT5DR1which removes trailing whitespace from the recently added virtio source files?
I'd prefer for my name not to appear for these changes as they only modify whitespace. You can use git apply or the patch command (remember to specify -p1 though) to apply the patch. It should be perfectly safe to apply as only whitespace is changed.
Thanks, John Scipione
