          If you say Y here, various routines which may sleep will become very
          noisy if they are called with a spinlock held.

+         Say Y here if you want the kernel to run a short self-test during
+         bootup. The self-test checks whether common types of locking bugs
+         are detected by debugging mechanisms or not. (if you disable
+         lock debugging then those bugs wont be detected of course.)
+         The following locking APIs are covered: spinlocks, rwlocks,
+         mutexes and rwsems.
