You could simply deprecate that interface but keep it for existing algorithms. Any new algorithms can then be queried through the crypto_user interface. The other option is to have a defined list of algorithms which is independent of the crypto API. For example, have a look at what IPsec does in net/xfrm/xfrm_algo.c. IPsec needs its own list because they come with annotations.
