cgroups: fix declaration of cgroup_mm_owner_callbacks
The choice of real/dummy declaration for cgroup_mm_owner_callbacks() shouldn't be based on CONFIG_MM_OWNER, but on CONFIG_CGROUPS. Otherwise kernel/exit.c fails to compile when something other than a cgroups controller selects CONFIG_MM_OWNER Signed-off-by: Paul Menage <menage@google.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
