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.
