| D | UP.rst | 6 A common misconception is that, on UP systems, the call_rcu() primitive
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

92 must match the flavor of rcu_barrier() with that of call_rcu(). If your
93 module uses multiple flavors of call_rcu(), then it must also use multiple

223 If the updater uses call_rcu() or synchronize_rcu(), then
254 disables BH when updaters use call_rcu() or synchronize_rcu().
256 8. Although synchronize_rcu() is slower than is call_rcu(), it
260 should be used in preference to call_rcu(). Furthermore,
270 code using call_rcu() should explicitly limit update rate in

150 express synchronize_rcu() in terms of the call_rcu() callback API.
214 The call_rcu() API is a callback form of synchronize_rcu(),
222 However, the call_rcu() API should not be used lightly, as use
227 of denial-of-service attacks. Code using call_rcu() should limit
355 synchronize_rcu() & call_rcu()
359 rcu_read_unlock(), synchronize_rcu(), and call_rcu() invocations in
361 to their callers and (2) call_rcu() callbacks may be invoked. Efficient
367 synchronize_rcu() and call_rcu() primitives used are the same for all three
499 In such cases, one uses call_rcu() rather than synchronize_rcu().
