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.
