/*
* 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.
*
* This test is done on the following configurations:
*
* - One core enqueuing, one core dequeuing
* - One core enqueuing, other cores dequeuing
* - One core dequeuing, other cores enqueuing
* - Half of the cores enqueuing, the other half dequeuing
*
* When only one core enqueues/dequeues, the test is done with the
* SP/SC functions in addition to the MP/MC functions.
*
* The test is done with different bulk size.
*
* On each core, the test enqueues or dequeues objects during
* TIME_S seconds. The number of successes and failures are stored on
* each core, then summed and displayed.
*
* The test checks that the number of enqueues is equal to the
* number of dequeues.
