Did you figure out a sumbission plan for this stuff?

At the very least it would be good to get those in right away.

I'm surprised nobody from VFIO has remarked on this, I think thety
won't like it

This sequence seems fairly stand alone, and in good shape as well

My advice is to put the done things on a branch and get Stephen to put

IMHO.
