          on the RCU infrastructure.  The kernel module may be built

+         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

+         available only when the RCU torture tests have been built
+         into the kernel.
