The dummy root will be repurposed to serve as the default unified hierarchy. Let's rename things in preparation. * s/cgroup_dummy_root/cgrp_dfl_root/ * s/cgroupfs_root/cgroup_root/ as we don't do fs part directly anymore * s/cgroup_root->top_cgroup/cgroup_root->cgrp/ for brevity This is pure rename.
