+ *      "OnlineNQ": rcu_barrier_callback() found online CPU, no callbacks.

+ *      "Inc2": rcu_barrier_callback() piggyback check counter incremented.
+ * The "cpu" argument is the CPU or -1 if meaningless, the "cnt" argument
+ * is the count of remaining callbacks, and "done" is the piggybacking count.
