It is similar to how some of the fops stuff works, eg the generic_file whatever functions everyone puts in. It would be improved a bit by making the ops struct mutable and populating it at runtime like we do in RDMA. Then the PCI ops and driver ops could be merged together without the repetition. Probably something that is more interesting if there are more drivers as it is a fair amount of typing to make. Jason
