I think the problem is, this adds an API between mm and balloon
device that is pretty complex: consider that previously we literally
only used alloc_page, __free_page and page->lru field.
So you end up with a problem: mm bits don't do anything
by themselves so mm people aren't very interested and
don't know about virtio anyway, while
we virtio device driver people lack a clue about compaction.
Having said that I think I'm getting my head about some of the issues so
I commented and the patchset is hopefully getting there.
