   - Why do we have to bump module refcount for 'struct sock' with
     _default_ callbacks ?

Nothing says that just because a sock uses default callbacks, it can't
be referenced in other ways by the implementation module, for example
it can sit in the protocol hash tables and that by itself requires
a module reference.
