From 00918b6ab89df8984ca06397cb77994dabd73f9b Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 10 Aug 2010 18:03:05 -0700 Subject: [PATCH] memcg: remove nid and zid argument from mem_cgroup_soft_limit_reclaim() mem_cgroup_soft_limit_reclaim() has zone, nid and zid argument. but nid and zid can be calculated from zone. So remove it.
