名称描述
rcu_implicit_dynticks_qsReturn true if the specified CPU has passed through a quiescent* state by virtue of being in or having passed through an dynticks* idle state since the last call to dyntick_save_progress_counter()* for this same CPU, or by virtue of having been offline.
call_rcuPost an RCU callback to be invoked after the end of an RCU grace* period. But since we have but one CPU, that would be after any* quiescent state.
