BTW: Why do you need these stub implementations at all?
If I read your code correctly it is because you're linking against the whole net/ directory.
Let's take register_filesystem() again as example. net/socket.c references it in sock_init().
Maybe it would make sense to split socket.c into two files, net/socket.c and net/sockfs.c.
Such that you could link only net/socket.o.
Of course you'd have to convince networking folks first. :D

By linking selectively objects files from net/ you could get rid of a lot unneeded stubs.

Thanks,
