Use this option to offload callback processing from all CPUs by default, in the absence of the rcu_nocbs or nohz_full boot parameter. This also avoids the need to use any boot parameters to achieve the effect of offloading all CPUs on boot.

Say Y here if you want offload all CPUs by default on boot. Say N here if you are unsure.
