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 <[email protected]> and Cedric Le Goater <[email protected]>.

And the author of net/sched/cls_cgroup.c is Thomas Graf <[email protected]>,

And the maintainer of kernel/ns_cgroup.c and security/device_cgroup.c is Serge E. Hallyn <[email protected]>.
