From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: [patch] mm: fix vmstat names-values off-by-one
"mm/mpol: Remove NUMA_INTERLEAVE_HIT" removed the NUMA_INTERLEAVE_HIT
item from the zone_stat_item enum, but left the corresponding name
string for it in the vmstat_text array. As a result, all counters
that follow it have their name offset by one from their value.
