Subject: mm/page_alloc: split per cpu page lists and zone stats -fix
mm/ is not W=1 clean for allnoconfig but the patch "mm/page_alloc: Split
per cpu page lists and zone stats" makes it worse with the following
warning
mm/vmstat.c: In function `zoneinfo_show_print':
mm/vmstat.c:1698:28: warning: variable `pzstats' set but not used [-Wunused-but-set-variable]
struct per_cpu_zonestat *pzstats;
^~~~~~~
This is a fix to the mmotm patch
mm-page_alloc-split-per-cpu-page-lists-and-zone-stats.patch.
