Well, YES :)
In addition to what you mentioned, I believe it would be possible to
avoid the duplication of global vs per-cgroup LRU lists. global
scanning would translate into proportional scanning of all per-cgroup
lists. If we could get that done, it would IMO become reasonable to
integrate back the remaining few page_cgroup fields into struct page
itself...
