Subject: [patch 054/101] mm: show node_pages_scanned per node, not zone
Date: Thu, 28 Jul 2016 15:47:14 -0700 [thread overview]
Message-ID: <579a8b72.0o55wLn4eMMwcX2/%akpm@linux-foundation.org> (raw)
From: Minchan Kim <minchan@kernel.org>
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.
