i guess you could do that but it'd soon run into some sort of combinatorial explosion ;).

so in this case what you can do is similar to what PaX does in drivers/ata/libata-core.c:

-       ops->inherits = NULL;
+       ((struct ata_port_operations *)ops)->inherits = NULL;

this cast is a good way to document that you're doing something special (kernel
devs would say 'fishy' probably ;).
