I can't see that far ahead too clearly, but I do think that at some point we'll actually distinguish between folio flags and page flags. For example, we won't have a FolioHWPoison, because we won't keep a folio together if one page in it has become defective. Nor will we have a PageUptodate because we'll only care about whether a folio is uptodate. And at that point, we won't want page flag policies.
