          callbacks are executed in batch periodically after a grace period.
          Do _not_ use defer_rcu() within a read-side critical section, because
          it may call synchronize_rcu() if the thread queue is full.
+       * Provides defer_rcu_ratelimit() primitive, which acts just like
+         defer_rcu(), but takes an additional rate limiter callback forcing
+         synchronized callback execution of the limiter returns non-zero.
+       * Requires that rcu_defer_barrier() must be called in library destructor
+         if a library queues callbacks and is expected to be unloaded with
+         dlclose().
+       * Its API is currently experimental. It may change in future library
+         releases.
