If the interrupt simulation status flag is set, return EBUSY.
如果设置了中断模拟状态标志，它就会返回EBUSY。
These extra routines are required only for this interrupt simulation.
这些附加例程只用于中断模拟。
This scenario arises when interrupt simulation is already in progress.
当中断模拟早已运行时，就会出现这种情况。
Iteration_count is the count to control the number of iteration of interrupt simulation.
iteration_count是控制中断模拟循环次数的计数器。
Set the interrupt simulation status flag to indicate that interrupt simulation is in progress.
设置中断模拟状态标志，通知中断模拟正在运行。
Once the interrupts are generated, reset the interrupt simulation status flag and return success.
中断生成之后，就重新设置中断模拟状态标志，并返回成功。
A new ioctl command should be added to the device driver to control the interrupt simulation from the test application.
ioctl命令应该添加到设备驱动程序中，这样就可以从测试应用程序中控制对中断的模拟了。
A separate ioctl command should be introduced to have control over interrupt simulation (see the section on the ioctl interface).
我们应该使用一个单独的ioctl命令来对中断模拟进行控制(请参阅ioctl接口一节的内容)。
