+ help
+ This option makes grace-period initialization block for a
+ few jiffies between initializing each pair of consecutive
+ rcu_node structures. This helps to expose races involving
+ grace-period initialization, in other words, it makes your
+ kernel less stable. It can also greatly increase grace-period
+ latency, especially on systems with large numbers of CPUs.
+ This is useful when torture-testing RCU, but in almost no
+ other circumstance.

+ Say Y here if you want your system to crash and hang more often.
+ Say N if you want a sane system.
