Name
rcu_barrier —
Wait until all in-flight call_rcu callbacks complete.
Synopsis
void rcu_barrier ( | void); |
Description
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.
