Acked-by: Vlastimil Babka <>

Actually looking at the git version, which has also this:

 static __always_inline void update_lru_size(struct lruvec *lruvec,
                                enum lru_list lru, enum zone_type zid,
-                               int nr_pages)
+                               long nr_pages)

Why now and here? Some of the functions called from update_lru_size()
still take int so this looks arbitrary?
