memcg: move mem_cgroup_is_root upwards
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 Signed-off-by: Michal Hocko <mhocko@suse.cz> Cc: Glauber Costa <glommer@parallels.com> Cc: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
