Subject: [PATCH 16/27] mm: Move page mapped accounting to the node
Date: Thu, 9 Jun 2016 19:04:32 +0100 [thread overview]
Message-ID: <1465495483-11855-17-git-send-email-mgorman@techsingularity.net> (raw)
In-Reply-To: <1465495483-11855-1-git-send-email-mgorman@techsingularity.net>
Reclaim makes decisions based on the number of file pages that are mapped but
it's mixing node and zone information. Account NR_FILE_MAPPED pages on the node.
