This option provides a kernel module that runs torture tests
on the RCU infrastructure. The kernel module may be built
after the fact on the running kernel to be tested, if desired.
+ Say Y here if you want RCU torture tests to be built into
+ the kernel.
Say M if you want the RCU torture tests to build as a module.
Say N if you are unsure.

+ This option provides a way to build the RCU torture tests
+ directly into the kernel without them starting up at boot
+ time. You can use /proc/sys/kernel/rcutorture_runnable
+ to manually override this setting. This /proc file is
+ available only when the RCU torture tests have been built
+ into the kernel.
+
+ Say Y here if you want the RCU torture tests to start during
+ boot (you probably don't).
+ Say N here if you want the RCU torture tests to start only
+ after being manually enabled via /proc.
