cgroup/cpuset: simplify the percpu kthreads check in update_tasks_cpumask()
kthread_is_per_cpu() can be called directly without checking whether PF_KTHREAD is set in task->flags. So remove PF_KTHREAD check to make code more concise. Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Reviewed-by: Waiman Long <longman@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>
