Handling interrupts in spidev

Hello,           I am using a custom ARM board. I have a SPI slave device and using the spidev_test utility I am able to do ioctls on the slave device. However, I have a problem. The SPI slave device has an interrupt pin and I want to process the interrupt and send some data into the userspace when I receive the interrupt. Can anybody please suggest me a way to do this using spidev driver? Regards, Amit.
