Hi! I've just started looking at this. Patch #1 modifies linux/virtio_crypto.h which if I compare with the (almost) latest linux master is different. Thus I would expect a corresponding kernel patch set too, but I haven't received one, nor did I find a reference in the cover letter. I think if I want to test the new features I need the kernel counter-part too, or? Could you point me to the kernel counterpart?
