| 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
30 This same problem can occur if call_rcu() is invoked from a hardware

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

18 Since call_rcu() never blocks, this code can safely be used from within
29 Unloading Modules That Use call_rcu()
71 For example, if it uses call_rcu(), call_srcu() on srcu_struct_1, and
151 RCU callbacks rarely include calls to call_rcu(). However, the rcutorture
172 module invokes call_rcu() from timers, you will need to first refrain
177 Of course, if your module uses call_rcu(), you will need to invoke
180 and on the same srcu_struct structure. If your module uses call_rcu()
