| D | UP.txt | 4 A common misconception is that, on UP systems, the call_rcu() primitive
20 which deletes element B, and then invokes call_rcu() to free element B
23 Now, if call_rcu() were to directly invoke its arguments, then upon return
28 This same problem can occur if call_rcu() is invoked from a hardware

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

184 module invokes call_rcu() from timers, you will need to first cancel all

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
