memcontrol: move mm_cgroup to header file
Inline functions must preceed their use, so mm_cgroup() should be defined in linux/memcontrol.h. include/linux/memcontrol.h:48: warning: 'mm_cgroup' declared inline after being called include/linux/memcontrol.h:48: warning: previous declaration of 'mm_cgroup' was here [akpm@linux-foundation.org: build fix] [akpm@linux-foundation.org: nuther build fix] Cc: Balbir Singh <balbir@linux.vnet.ibm.com> Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
