22 which deletes element B, and then invokes call_rcu() to free element B
25 Now, if call_rcu() were to directly invoke its arguments, then upon return

43 deletes element B from the list, then passes it to call_rcu() for deferred
45 RCU usage, since call_rcu() must wait for a grace period to elapse.
46 Therefore, in this case, allowing call_rcu() to immediately invoke
48 underlying RCU, namely that call_rcu() defers invoking its arguments until

| D | whatisRCU.txt | 126 c. synchronize_rcu() / call_rcu()
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
209 of denial-of-service attacks. Code using call_rcu() should limit

332 rcu_read_unlock(), synchronize_rcu(), and call_rcu() invocations in
334 to their callers and (2) call_rcu() callbacks may be invoked. Efficient
340 sychronize_rcu() and call_rcu() primitives used are the same for all three
467 In such cases, one uses call_rcu() rather than synchronize_rcu().
