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

Hi Andrew,

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

mm/memcontrol.c:5269:12: error: 'CFTYPE_INSANE' undeclared here (not in a function)
   .flags = CFTYPE_INSANE,
            ^

Caused by commit 8fa6a8baeffc ("memcg: deprecate memory.force_empty
knob") interacting with commits a8ddc8215e1a ("cgroup: distinguish the
default and legacy hierarchies when handling cftypes") and 05ebb6e60f04
("cgroup: make CFTYPE_ONLY_ON_DFL and CFTYPE_NO_ internal to cgroup
core") from the cgroup tree.

I applied the following fix up patch:
