If these are more features, you can just post them on list noting "next" in subject and saying "this is on top of vhost tree" after --. I don't know how to make 0-day figure out where to apply such dependent patches unfortunately.> > -- > Thanks, > > David / dhildenb

I can squash them and resend, makes things easier. The other stuff I have are extensions, I will send as add-on. Thanks! -- Thanks, David / dhildenb
