The patch titled Subject: mm/page_alloc: split per cpu page lists and zone stats -fix -fix has been added to the -mm tree. Its filename is mm-page_alloc-split-per-cpu-page-lists-and-zone-stats-fix-fix.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/mm-page_alloc-split-per-cpu-page-lists-and-zone-stats-fix-fix.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/mm-page_alloc-split-per-cpu-page-lists-and-zone-stats-fix-fix.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mel Gorman <mgorman@xxxxxxxxxxxxxxxxxxx> Subject: mm/page_alloc: split per cpu page lists and zone stats -fix -fix 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 `refresh_cpu_vm_stats': mm/vmstat.c:785:34: warning: unused variable `pcp' [-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.
