			You will not be able to mount the cpuset hierarchy if the unified cgroupv2 hierarchy exists, and <tt>cpuset</tt> is present in any <tt>cgroup.subtree_control</tt> node (the mount will fail with <tt>EBUSY</tt>). Likewise, a mounted cpuset hierarchy will prevent <tt>cpuset</tt> from being added to a cgroupv2 <tt>cgroup.subtree_control</tt> (the write will fail with <tt>ENOENT</tt>).
