So we will have two competing crypo stacks in the kernel?

Having a lightweight crypto API is a good thing but I really don't like the idea
of having zinc parallel to the existing crypto stack.
And I strongly vote that Herbert Xu shall remain the maintainer of the whole
crypto system (including zinc!) in the kernel.
