+ rcupdate.rcu_expedited= [KNL]
+ Use expedited grace-period primitives, for
+ example, synchronize_rcu_expedited() instead
+ of synchronize_rcu(). This reduces latency,
+ but can increase CPU utilization, degrade
+ real-time latency, and degrade energy efficiency.
+
+ rcupdate.rcu_cpu_stall_suppress= [KNL]
+ Suppress RCU CPU stall warning messages.
+
+ rcupdate.rcu_cpu_stall_timeout= [KNL]
+ Set timeout for RCU CPU stall warning messages.
