  * Tracepoint for _rcu_barrier() execution.  The string "s" describes
  * the _rcu_barrier phase:
- *     "Begin": rcu_barrier_callback() started.
- *     "Check": rcu_barrier_callback() checking for piggybacking.
- *     "EarlyExit": rcu_barrier_callback() piggybacked, thus early exit.
- *     "Inc1": rcu_barrier_callback() piggyback check counter incremented.
- *     "Offline": rcu_barrier_callback() found offline CPU
- *     "OnlineNoCB": rcu_barrier_callback() found online no-CBs CPU.
- *     "OnlineQ": rcu_barrier_callback() found online CPU with callbacks.
- *     "OnlineNQ": rcu_barrier_callback() found online CPU, no callbacks.
+ *     "Begin": _rcu_barrier() started.
+ *     "Check": _rcu_barrier() checking for piggybacking.

+ *     "OfflineNoCB": _rcu_barrier() found callback on never-online CPU

  *     "IRQ": An rcu_barrier_callback() callback posted on remote CPU.
  *     "CB": An rcu_barrier_callback() invoked a callback, not the last.
  *     "LastCB": An rcu_barrier_callback() invoked the last callback.
- *     "Inc2": rcu_barrier_callback() piggyback check counter incremented.
+ *     "Inc2": _rcu_barrier() 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.
