Subject: [PATCH 7/8] cgroup: rename functions for consistency
Now that v1 functions are separated out, rename some functions for
consistency.
cgroup_dfl_base_files -> cgroup_base_files
cgroup_legacy_base_files -> cgroup1_base_files
cgroup_ssid_no_v1() -> cgroup1_ssid_disabled()
cgroup_pidlist_destroy_all -> cgroup1_pidlist_destroy_all()
cgroup_release_agent() -> cgroup1_release_agent()
check_for_release() -> cgroup1_check_for_release()
Signed-off-by: Tejun Heo <tj@...nel.org>
