-          This option selects the classic RCU implementation that is
-          designed for best read-side performance on non-realtime
-          systems.  Classic RCU is the default.  Note that the
-          PREEMPT_RCU symbol is used to select/deselect this option.
+          This option provides tracing for the TREE_RCU implementation,
