+         If you say Y here, additional code will be inserted into the
+         scheduler and related routines to collect statistics about
+         scheduler behavior and provide them in /proc/schedstat.  These
+         stats may be useful for both tuning and debugging the scheduler

+         application, you can say N to avoid the very slight overhead
+         this adds.

-       help
-         Kprobes allows you to trap at almost any kernel address and
-         execute a callback function.  register_kprobe() establishes
-         a probepoint and specifies the callback.  Kprobes is useful
