Btw, why isn't the code in __page_set_anon_rmap() also doing this cleaner version (ie a single "if (PageAnon(page)) return;" up front)? The comments in that function are also some alien language translated to english by some broken automatic translation service. Could somebody clean up that function and come up with a comment that actually parses as English and makes sense?
