You have a graph, because a graph is just nodes + links. I did _not_
propose a full generic graph structure, the link pointer would be in the
class/type specific structure only. Like how we have the plane->crtc or
connector->crtc links already like that (which already _is_ is full blown
graph).
Maybe explain what exactly you're thinking under "do graphs here" so I
understand what you mean differently than me?
