Subject: [PATCH 28/31] mm: vmstat: replace __count_zone_vm_events with a zone id equivalent
Date: Fri, 1 Jul 2016 16:37:43 +0100 [thread overview]
Message-ID: <1467387466-10022-29-git-send-email-mgorman@techsingularity.net> (raw)
In-Reply-To: <1467387466-10022-1-git-send-email-mgorman@techsingularity.net>
This is partially a preparation patch for more vmstat work but it also has
the slight advantage that __count_zid_vm_events is cheaper to calculate
than __count_zone_vm_events().
