Subject: zone_statistics: Use hot node instead of cold zone_pgdat
Date: Mon, 18 Sep 2006 19:50:06 -0700 (PDT) [thread overview]
Message-ID: <Pine.LNX.4.64.0609181949240.2078@schroedinger.engr.sgi.com> (raw)
Now that we have the node in the hot zone of struct zone we can avoid accessing
zone_pgdat in zone_statistics.
