I think we should finish the conversion of the only in-kernel user of RSA before we add the user-space interface. Otherwise this unnecessarily ties our hands to the current API. For example, do we want an SG interface for the input and output? As it stands even if a hardware device came with SG support we would not be able to use it. Tadeusz, can you confirm again that qat does not support SG with respect to RSA input and output?
