- * Ring
- * ====
- *
- * #. Basic tests: done on one core:
- *
- *    - Using single producer/single consumer functions:
- *
- *      - Enqueue one object, two objects, MAX_BULK objects
- *      - Dequeue one object, two objects, MAX_BULK objects
- *      - Check that dequeued pointers are correct
- *
- *    - Using multi producers/multi consumers functions:
- *
- *      - Enqueue one object, two objects, MAX_BULK objects
- *      - Dequeue one object, two objects, MAX_BULK objects
- *      - Check that dequeued pointers are correct
- *
- *    - Test watermark and default bulk enqueue/dequeue:
- *
- *      - Set watermark
- *      - Set default bulk value
- *      - Enqueue objects, check that -EDQUOT is returned when
- *        watermark is exceeded
- *      - Check that dequeued pointers are correct
- *
- * #. Check live watermark change
- *
- *    - Start a loop on another lcore that will enqueue and dequeue
- *      objects in a ring. It will monitor the value of watermark.
- *    - At the same time, change the watermark on the master lcore.
- *    - The slave lcore will check that watermark changes from 16 to 32.
- *
- * #. Performance tests.
- *
- * Tests done in test_ring_perf.c
