-/**
- * @file sprmsched01/tasks.c
- *
- * @brief A heuristic example to demonstrate how the postponed jobs are handled.
- *
- * 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.
- *
