Just to clarify. We can create a dir from the kernel already. It is no
problem. I am doing that in this patchset with configfs_register_group.

What Bart was requesting originally and what is missing is being able to
add a symlink from the kernel.

I have not fully looked into it, but I think it would be something like
taking part of configfs_symlink and making it so we can call it with
config_items for the 2 items to be symlinked.
