+ * @brief This test case collection provides SMP-specific validation test cases
+ *   for requirements of the @ref RTEMSAPIClassicTasks.
+ *
+ * This test case performs the following actions:
+ *
+ * - Validate the home scheduler of tasks created by rtems_task_create() and
+ *   constructed by rtems_task_construct() on scheduler B.
+ *
+ *   - Move runner from scheduler A to B.
+ *
+ *   - Create a task.  Check that the home scheduler of the created task is
+ *     scheduler B.
+ *
+ *   - Construct a task.  Check that the home scheduler of the constructed task
+ *     is scheduler B.
+ *
+ *   - Restore runner scheduler.
