Subject: Interrupt handler registration for multiple devices

Hi,

I want to write a driver that will handle multiple devices. These
devices will share the IRQ line. Do I need to register my (same)
interrupt handler as many times as the number of devices(by calling
request_irq())?

Also an unrelated query. Can I sleep after a call to preempt_kernel()??

TIA,

Rick
