Subject: linux-next: build warning after merge of the akpm-current tree

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
