Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

mm/madvise.c: In function 'madvise_inject_error':
mm/madvise.c:875:15: warning: unused variable 'zone' [-Wunused-variable]
  875 |  struct zone *zone;
      |               ^~~~

Introduced by commit

  51fe27319785 ("mm,hwpoison: drop unneeded pcplist draining")
