Description

When a thread obtains a semaphore with a priority ceiling lower than the threads priority, RTEMS does not return a error.

Suggestion:

  1. Change the RTEMS code to verify (inside the rtems_semaphore_obtain directive) if the semaphore priority ceiling and threads priority are coherent.
