  brief: |
    Release the mutex.

test-setup:
  brief: |
    Let one task wait on the mutex.
  code: |
    ObtainMutex( ctx->mutex_id );
    Send( ctx, EVENT_OBTAIN );
    SetPriority( ctx->worker_id, PRIO_LOW );
    Send( ctx, EVENT_RELEASE );

test-teardown:
  brief: |
    Restore the worker priority.  Discard samples interrupted by a clock tick.
  code: |
    T_quiet_rsc( ctx->status, RTEMS_SUCCESSFUL );

    SetPriority( ctx->worker_id, PRIO_HIGH );

  While the execution environment is ${.:/environment}, while the semaphore is
  a priority inheritance mutex, while the measurement sample is the runtime of
  exactly one successful call to ${../if/release:/name} which does unblock
  exactly one waiting task which does not preempt the caller, when exactly
  ${../val/perf:/params/sample-count} samples are collected, the
  ${.:/limit-kind} shall be ${.:/limit-condition}.
