Prev: [PATCH 4/5] memcg: remove nid and zid argument from mem_cgroup_soft_limit_reclaim()
Next: trace: uprobes trace_event interface
From: KOSAKI Motohiro on 29 Jul 2010 01:30
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.
