Lazy RCU callbacks are those which RCU can
prove do nothing more than free memory.
+ rcutree.rcu_kick_kthreads= [KNL]
+ Cause the grace-period kthread to get an extra
+ wake_up() if it sleeps three times longer than
+ it should at force-quiescent-state time.
+ This wake_up() will be accompanied by a
+ WARN_ONCE() splat and an ftrace_dump().

rcuperf.gp_exp= [KNL]
Measure performance of expedited synchronous
grace-period primitives.
