RE: [RFC]confusions about 'struct' define

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

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?
