May be we should fix it like this:

F: include/linux/cgroup.h
F: kernel/cgroup.c
F: kernel/cgroup_debug.c

?

Since the authors of kernel/cgroup_freezer.c are Matt Helsley <matthltc@us.ibm.com>
and Cedric Le Goater <clg@fr.ibm.com>.

And the author of net/sched/cls_cgroup.c is Thomas Graf <tgraf@suug.ch>,

And the maintainer of kernel/ns_cgroup.c and security/device_cgroup.c is
Serge E. Hallyn <serue@us.ibm.com>.

And this belongs to memory resource controller (grep 'MEMORY RESOURCE CONTROLLER'
in MAINTAINERS). The maintainers of mm/page_cgroup.c and mm/memcontrol.c are
Balbir and Kamezawa.
