Prev: [PATCH 0/4] memcg reclaim tracepoint v2
Next: [PATCH 4/4] memcg: add mm_vmscan_memcg_isolate tracepoint
From: KOSAKI Motohiro on 25 Jul 2010 23:10 Mel Gorman recently added some vmscan tracepoints. Unfortunately they are covered only global reclaim. But we want to trace memcg reclaim too. Thus, this patch convert them to DEFINE_TRACE macro. it help to reuse tracepoint definition for other similar usage (i.e. memcg). This patch have no functionally change.
