Openssl uses init->update->final sequencing, and it would be nice to have

You're referring to algif_hash, right? If so it'd be much easier
to implement the buffering in user-space.

algif_hash / cryptodev can both be used via openssl, but I think both of them have the same limitation, yeah.

Anyways, sounds like you prefer dropping any hacks towards this from the kernel driver, so I'll just do that and consider patching the upper layers for openssl maybe...
