From 6104621de4ffd94d66eae59cedc70d742a92316b Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Tue, 29 May 2012 15:07:05 -0700 Subject: mm: memcg: remove obsolete statistics array boundary enum item MEM_CGROUP_STAT_DATA is a leftover from when item counters were living in the same array as ever-increasing event counters. It's no longer needed, use MEM_CGROUP_STAT_NSTATS to iterate over the stat array.
