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

this is something that we've been avoided: we weren't able
to estimate how much such splits will expand.

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

now I'm trying to minimize those stubs by reusing the original
codes (i.e., fs/filesystems.c for register_filesystem()). I
will let you know once I've done (maybe v2 RFC if you think
it's better ?)
