+
+    cgroup2: use new fstype for unified hierarchy
+
+    Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and
+    is replaced by a new fstype "cgroup2".
+
+    With this patch, systemd no longer supports the old (unstable) way of
+    doing unified hierarchy with __DEVEL__sane_behavior and systemd now
+    requires Linux v4.4 for unified hierarchy.
+
+    Non-unified hierarchy is still the default and is unchanged by this
+    patch.
