Subject: [PATCH] mm: memcg: move cgroup v1 oom handling code into memcontrol-v1.c: fixup
This is a small fixup for the commit
"mm: memcg: move cgroup v1 oom handling code into memcontrol-v1.c".
I forgot to actually move two functions mem_cgroup_node_nr_lru_pages()
and mem_cgroup_nr_lru_pages() into mm/memcontrol-v1.c, so that they remain
in mm/memcontrol.c and their commented out duplicated versions in
mm/memcontrol-v1.c.
Andrew, can you, please, squash it into the original commit?
I checked that the rest of mm-unstable tree can be rebased
automatically without any merge conflicts.
