- * Name:  sched_unlock
- *
- * Description:
- *   This function decrements the preemption lock count.  Typically this
- *   is paired with sched_lock() and concludes a critical section of
- *   code.  Preemption will not be unlocked until sched_unlock() has
- *   been called as many times as sched_lock().  When the lockcount is
- *   decremented to zero, any tasks that were eligible to preempt the
- *   current task will execute.
- *
