       schedule_timeout - sleep until timeout


       signed long __sched schedule_timeout  (signed long timeout);


              timeout value in jiffies


       Make  the  current  task  sleep until timeout jiffies have elapsed. The
       routine will return immediately unless the current task state has  been
       set (see set_current_state).

       You can set the task state as follows -

        TASK_UNINTERRUPTIBLE - at least timeout jiffies are guaranteed to pass
       before the routine returns. The routine will return 0

        TASK_INTERRUPTIBLE - the routine may  return  early  if  a  signal  is
       delivered  to  the  current  task.  In  this case the remaining time in
       jiffies will be returned, or 0 if the timer expired in time

       The current task state is  guaranteed  to  be  TASK_RUNNING  when  this
       routine returns.

       Specifying  a  timeout  value of MAX_SCHEDULE_TIMEOUT will schedule the
       CPU away without a bound on the timeout. In this case the return  value
       will be MAX_SCHEDULE_TIMEOUT.

       In all cases the return value is guaranteed to be non-negative.
