From: Minchan Kim <minchan@xxxxxxxxxx>
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.
