From: Minchan Kim <minchan@xxxxxxxxxx> Subject: mm: show node_pages_scanned per node, not zone The node_pages_scanned represents the number of scanned pages of node for reclaim so it's pointless to show it as kilobytes. As well, node_pages_scanned is per-node value, not per-zone. This patch changes node_pages_scanned per-zone-killobytes with per-node-count.
