General informations

Help text

This option causes rcutorture to check the desired rcutorture reader state for each segment against the actual context. Note that PREEMPT_COUNT must be enabled if the preempt-disabled and bh-disabled checks are to take effect, and that PREEMPT_RCU must be enabled for the RCU-nesting checks to take effect. These checks add overhead, and this Kconfig options is therefore disabled by default.

Say Y here if you want rcutorture reader contexts checked. Say N if you are unsure.
