/**
* @file sprmsched01/init.c
* @brief A heuristic example to demonstrate how the postponed jobs are handled.
*
* @brief A init task body for sprmsched01 example.
* Given two tasks with implicit deadline under fixed-priority scheudling.
* Task 1 has (6, 10) and task 2 has (1, 2), where (execution time, deadline/period).
* To force deadline misses, we reverse the rate-monotonic priority assignment
* and only execute the highest priority task twice.
*
* In the original implementation in v4.11, no matter how many periods are
* expired, RMS manager only releases a job with a shifted deadline assignment
* in the watchdog. As the results written in sprmsched01.scn, we can see that
* the timeout of task 2 period will be detected right after Job3 of Task2 is finished.
* If the overrun handling is correct, the status of task 2 period will return back to
* RTEMS_SUCCESSFUL after periodically releasing those postponed jobs (the last one is Job 9).
*
* Otherwise, we can see that the release time of Job 4 is no longer periodic,
* and the RTEMS returns back to RTEMS_SUCCESSFUL right after Job 4 is finished
* without releasing all the other postponed jobs.
*
