Hi all, After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning: mm/memcontrol.c: In function 'invalidate_reclaim_iterators': mm/memcontrol.c:1160:11: warning: suggest parentheses around assignment used as truth value [-Wparentheses] } while (memcg = parent_mem_cgroup(memcg)); ^~~~~ Introduced by commit c48a2f5ce935 ("mm/memcontrol.c: fix use after free in mem_cgroup_iter()") -- Cheers, Stephen Rothwell
