Help text

This option does not force any of the CPUs to be no-CBs CPUs. Only CPUs designated by the rcu_nocbs= boot parameter will be no-CBs CPUs, whose RCU callbacks will be invoked by per-CPU kthreads whose names begin with "rcuo". All other CPUs will invoke their own RCU callbacks in softirq context.

Select this option if you want to choose no-CBs CPUs at boot time, for example, to allow testing of different no-CBs configurations without having to rebuild the kernel each time.
