This might be the case of cyclic dependency where header files defining these structures are also including this .h file.

Hi Gaurav,

Those are forward declarations as they are being used in defining struct bus_attribute. It's nothing special about GNU-C. That's the case for ANSI-C too. Pretty standard.

Hmmm.., that is to say, they may be used before definitions in this file or defined in other files like 'struct iommu_ops;' field (Actually, i can not find this field's
definition in this file). However, if it has been defined in other header files, we need
not declare here, right?
