132 express synchronize_rcu() in terms of the call_rcu() callback API.
196 	The call_rcu() API is a callback form of synchronize_rcu(),
204 	However, the call_rcu() API should not be used lightly, as use

455 In such cases, one uses call_rcu() rather than synchronize_rcu().
456 The call_rcu() API is as follows:
458 	void call_rcu(struct rcu_head * head,

518 The use of call_rcu() permits the caller of foo_update_a() to
525 that we are now using call_rcu() rather than synchronize_rcu():
