The following locking APIs are covered: spinlocks, rwlocks,
mutexes and rwsems.

+ This option provides a kernel module that runs torture tests
+ on kernel locking primitives. The kernel module may be built
+ after the fact on the running kernel to be tested, if desired.

+ Say Y here if you want kernel locking-primitive torture tests
+ to be built into the kernel.
+ Say M if you want these torture tests to build as a module.
+ Say N if you are unsure.
