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.
