rcu_barrier9
Wait until all in-flight call_rcu callbacks complete.
Usage
void rcu_barrier(void);
Arguments
void
no arguments
Overview
Note that this primitive does not necessarily wait for an RCU grace period to complete. For example, if there are no RCU callbacks queued anywhere in the system, then rcu_barrier is within its rights to return immediately, without waiting for anything, much less an RCU grace period.
