+ 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.
+
+ Say Y here if you want the RCU performance tests to start during
+ 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.
