bottomhalf方法可以将设备驱动程序中的工作延迟到中断处理后执行。
A bottom half is a way to defer work from interrupt handling to be done later in a device driver.
驱动程序将根据中断的优先级次序来执行数据操作。
Your driver will perform some data manipulation based on a sequence of interrupts.
该模块是实时任务的，采用中断驱动状态转移的机制，提高了程序执行的效率。
This module is based on real Real-Time Task and adopts Interruptions Driving States Shifting mechanism. Consequently it improves the efficiency of executing programs.
