From 16709d1de1954475356a65848f80a01581b4903c Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Thu, 28 Jul 2016 15:46:56 -0700 Subject: [PATCH] mm: vmstat: replace __count_zone_vm_events with a zone id equivalent 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().
