- * Theory of operations:
- * 1) We use a list, protected by a spinlock, to add
- *    new entries from both BH and non-BH context.
- * 2) In order to keep spinlock held for a small delay,
- *    we use a second list where are stored long lived
- *    entries, that are handled by the garbage collect thread
- *    fired by a workqueue.
- * 3) This list is guarded by a mutex,
- *    so that the gc_task and dst_dev_event() can be synchronized.

- * We want to keep lock & list close together
- * to dirty as few cache lines as possible in __dst_free().
- * As this is not a very strong hint, we dont force an alignment on SMP.
