-------------------------------------------------
Patch a222f3415868 ("mm: generalize putback scan functions") has combined move_active_pages_to_lru() and putback_inactive_pages() into single move_pages_to_lru(). But we didn't backport this patch so move_active_pages_to_lru() is still existed. When We moved mem_cgroup_uncharge() in 7ae88534cdd9 ("mm: move mem_cgroup_uncharge out of __page_cache_release()"), move_active_pages_to_lru() should be changed together.
