-/*
- * rwlock test
- * ===========
- *
- * - There is a global rwlock and a table of rwlocks (one per lcore).
- *
- * - The test function takes all of these locks and launches the
- *   ``test_rwlock_per_core()`` function on each core (except the master).
- *
- *   - The function takes the global write lock, display something,
- *     then releases the global lock.
- *   - Then, it takes the per-lcore write lock, display something, and
- *     releases the per-core lock.
- *   - Finally, a read lock is taken during 100 ms, then released.
- *
- * - The main function unlocks the per-lcore locks sequentially and
- *   waits between each lock. This triggers the display of a message
- *   for each core, in the correct order.
- *
- *   Then, it tries to take the global write lock and display the last
- *   message. The autotest script checks that the message order is correct.
