在使用wait_for_completion()的_timeout()或_killable()/_interruptible()变体时,应特别小心,因为必须确保在所有相关活动(complete()或reinit_completion())发生之前不会发生内存释放,即使这些等待函数由于超时或信号触发而提前返回。 通过调用init_completion()来初始化动态分配的完成对象: init_completion(&dynamic_obj...

(1) 进程在等待完成时处于不可中断状态,若使用wait_for_completion_interruptible表示可中断,如果进程被中断,则返回-ERESTARTSYS,否则返回0; (2) wait_for_completion_timeout表示等待事件的发生,并且提供超时设置,如果超过了这一设置,则取消等待,可防止无限等待;如果在超时之前完成则返回剩余时间,否则返回0。
