Prev: [PATCH 3/7] memcg: nid and zid can be calculated from zone
Next: memcg: sc.nr_to_reclaim should be initialized
From: KOSAKI Motohiro on 16 Jul 2010 06:20 Currently, mem_cgroup_shrink_node_zone() initialize sc.nr_to_reclaim as 0. It mean shrink_zone() only scan 32 pages and immediately return even if it doesn't reclaim any pages. This patch fixes it.
