And here is another trivial patch on top of the previous patch.
I am not sure whether we care about such old compilers but the change
itself makes some sense on its own.

Subject: [PATCH] memcg: move mem_cgroup_is_root upwards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
kmem code uses this function and it is better to not use forward
declarations for static inline functions as some (older) compilers don't
like it:
gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux)
mm/memcontrol.c:421: warning: ‘mem_cgroup_is_root’ declared inline after being called
mm/memcontrol.c:421: warning: previous declaration of ‘mem_cgroup_is_root’ was here
