Subject: vmscan: convert direct reclaim tracepoint to DEFINE_TRACE
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
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.
