- * vlib provides lock-free counters but those
- * - Have 16bits per-CPU counter, which may overflow.
- * - Would only increment.
- *
- * This is very similar to vlib counters, but may be used to count reference.
- * Such a counter includes an arbitrary number of counters. Each counter
- * is identified by its index. This is used to aggregate per-cpu memory.
- *
- * Warning:
- *   This reference counter is lock-free but is not race-condition free.
- *   The counting result is approximate and another mechanism needs to be used
- *   in order to ensure that an object may be freed.
