void(*)(struct rcu_head *rcu)  func

void call_rcu_sched ( struct rcu_head head,
void(*)(struct rcu_head *rcu)  func 

call_rcu_sched() - Queue an RCU for invocation after sched grace period. : structure to be used for queueing the RCU updates. : actual callback function to be invoked after the grace period

The callback function will be invoked some time after a full grace period elapses, in other words after all currently executing RCU read-side critical sections have completed. call_rcu_sched() assumes that the read-side critical sections end on enabling of preemption or on voluntary preemption. RCU read-side critical sections are delimited by :

  • rcu_read_lock_sched() and rcu_read_unlock_sched(), OR anything that disables preemption. These may be nested.
