Yeah, the vfio change is expected to break the build; the fix should be
easy (simple rename), and the code affected is deprecated anyway (there
hasn't been any upstream implementation that actually exposed the
interfaces). I think we should do that in a single commit to preserve
bisectability; I have not seen any patches posted yet to actually use
the new vfio migration interface, so a simple compile fixup should be
all that is needed.
