| |
mm/ is not W=1 clean for make allnoconfig but this patch accidentally made it worse for i386 with the warning
mm/vmstat.c: In function ârefresh_cpu_vm_statsâ: mm/vmstat.c:785:34: warning: unused variable âpcpâ [-Wunused-variable] struct per_cpu_pages __percpu *pcp = zone->per_cpu_pageset; ^~~
This is a second fix to the mmotm patch mm-page_alloc-split-per-cpu-page-lists-and-zone-stats.patch.
