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

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 ?)
