kthread_should_stop()返回should_stop标志。它用于创建的线程检查结束标志，并决定是否退出。线程完全可以在完成自己的工作后主动结束，不需等待should_stop标志。该函数定义在include/linux/kthread.h中，与其相关的还有：struct task_struct kthread_run(int (*threadfn)(void *data), void *data,c...
When using kthreads that call into svc_recv, we want to make sure that they do not block there for a long time when we're trying to take down the kthread. This patch changes svc_recv() to check kthread_should_stop() at the same places that it checks to see if it's signalled()...
