You might consider using a linear tree instead of the topic branches,
topics are tricky and I'm not sure it helps a small subsystem so much.
Conflicts between topics are a PITA for everyone, and it makes
handling conflicts with rc much harder than it needs to be.

At least I haven't felt a need for topics while running larger trees,
and would find it stressful to try and squeeze the entire patch flow
into only 3 weeks out of the 7 week cycle.

In any event, I'd like this on a branch so Alex can pull it too, I
guess it means Alex has to merge rc3 to VFIO as well?

Thanks for explaining
