Subject: [PATCH 26/27] mm: vmstat: Replace __count_zone_vm_events with a zone id equivalent
Date: Tue, 21 Jun 2016 15:16:05 +0100 [thread overview]
Message-ID: <1466518566-30034-27-git-send-email-mgorman@techsingularity.net> (raw)
In-Reply-To: <1466518566-30034-1-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().
