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") -- Cheers, Stephen Rothwell
