Hi all,

         First, I have to say sorry for my pool English , because I am not a native English speaker.

         I know this is too simple, but I have tried hours to get the definition (not  declaration) of irq_desc array in the interrupt subsys.

         Actually, I have been troubled in finding the definition. Because the array name( irq_desc) is same as the name of struct irq_desc.

         I think the irq_desc array is the core of interrupt subsys, so I didn’t describe it in details.  I tried describing my question , if there is

something not clear, please let me know ,and I will try ….

         Sorry for my pool English again....
