-/*
- * Spinlock test
- * =============
- *
- * - There is a global spinlock and a table of spinlocks (one per lcore).
- *
- * - The test function takes all of these locks and launches the
- *   ``test_spinlock_per_core()`` function on each core (except the master).
- *
- *   - The function takes the global lock, display something, then releases
- *     the global lock.
- *   - The function takes the per-lcore lock, display something, then releases
- *     the per-core lock.
- *
- * - 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. The autotest script checks that
- *   this order is correct.
- *
- * - A load test is carried out, with all cores attempting to lock a single lock
- *   multiple times
