struct task_struct *kworker_task = kthread_run(kthread_worker_fn, &worker, "nvme%d", dev->instance); kworker_task->flags &= ~PF_NOFREEZE; is it safe to do like this ? i don't see an API to set other thread to be freezable . only set_freezable() , which set the current thread to be freezable . am i missing something ?
