-config RCU_TORTURE_TEST_SLOW_PREINIT
- bool "Slow down RCU grace-period pre-initialization to expose races"

- help
- This option delays grace-period pre-initialization (the
- propagation of CPU-hotplug changes up the rcu_node combining
- tree) for a few jiffies between initializing each pair of
- consecutive rcu_node structures. This helps to expose races
- involving grace-period pre-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
