I think what you're going to find out quickly when you upstream more is
that the community will not care about your downstream stuff. The
problem I have with this patch is that you're adding code that no-one is
using at the moment and with the crypto driver being redesigned, this
code may or may not get used, right? Let's focus on the getting the
crypto driver first.
