Message-Id: <1322062951-1756-7-git-send-email-hannes@cmpxchg.org> Date: Wed, 23 Nov 2011 16:42:29 +0100 From: Johannes Weiner <hannes@...xchg.org> To: Andrew Morton <akpm@...ux-foundation.org> Cc: KAMEZAWA Hiroyuki <kamezawa.hiroyu@...fujitsu.com>, Michal Hocko <mhocko@...e.cz>, Balbir Singh <bsingharora@...il.com>, cgroups@...r.kernel.org, linux-mm@...ck.org, linux-kernel@...r.kernel.org Subject: [patch 6/8] mm: memcg: remove unneeded checks from uncharge_page() From: Johannes Weiner <jweiner@...hat.com> mem_cgroup_uncharge_page() is only called on either freshly allocated pages without page->mapping or on rmapped PageAnon() pages. There is no need to check for a page->mapping that is not an anon_vma.
