| |
rcu_prepare_kthreads() is called when a CPU hotplug event happens. We can also spawn the nocb kthreads from this function. This is preparation for the next patch which remove the redundant check for rcu_scheduler_fully_active. This commit moves the spawning of nocb kthreads to rcu_prepare_kthreads().
