Hi Andrew,

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from kernel/fork.c:21:0:
include/linux/mempolicy.h: In function 'task_has_mempolicy':
include/linux/mempolicy.h:258:13: error: dereferencing pointer to incomplete type

And several more like that.

Caused by commit 9d15457f147d
("cpusets-stall-when-updating-mems_allowed-for-mempolicy-or-disjoint-nodemask-fix-2").

I have reverted that patch for today (and the following trivial patch
"cpusets-stall-when-updating-mems_allowed-for-mempolicy-or-disjoint-nodemask-fix-2-fix").
