From e17613c39b8894c164df782d0508c27ca559c24b Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Date: Mon, 9 Aug 2010 17:19:57 -0700 Subject: [PATCH] vmscan: convert mm_vmscan_lru_isolate to DEFINE_EVENT 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.
