This is difficult to read. Let's separate it out to two separate tables, cgroup_dfl_base_files[] and cgroup_legacy_base_files[], and use the appropriate one in cgroup_mkdir() depending on the hierarchy type. This makes tagging each file unnecessary. This patch doesn't introduce any behavior changes.
