+         This option provides a way to build the RCU performance tests
+         directly into the kernel without them starting up at boot time.
+         You can use /sys/module to manually override this setting.
+         This /proc file is available only when the RCU performance
+         tests have been built into the kernel.

+         boot (you probably don't).
+         Say N here if you want the RCU performance tests to start only
+         after being manually enabled via /sys/module.
