From cf4dcc3e9b374e1b61a7c22faf868707ce78d6a9 Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Mon, 9 Aug 2010 17:19:55 -0700 Subject: [PATCH] vmscan: convert direct reclaim tracepoint to DEFINE_TRACE 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.
