Subject: [PATCH 1/2 cgroup/for-3.20] cgroup: reorder SUBSYS(blkio) in
 cgroup_subsys.h

The scheduled cgroup writeback support requires blkio to be
initialized before memcg as memcg needs to provide certain blkcg
related functionalities.  Relocate blkio so that it's right above
memory.

Hello,

These are two trivial patches to prepare for the cgroup writeback
support.  Applying to cgroup/for-3.20.

Thanks.
