From cbf84b7add8103b92aaa84928e335df726bfc8da Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 6 Jan 2009 14:39:27 -0800 Subject: mm: further cleanup page_add_new_anon_rmap Moving lru_cache_add_active_or_unevictable() into page_add_new_anon_rmap() was good but stupid: we can and should SetPageSwapBacked() there too; and we know for sure that this anonymous, swap-backed page is not file cache.
