Thanks a lot for the review of the zcrypt patches. Its very good to know
that these base changes are ok with you.

Regarding merging: yes, this should be a tip branch then. Before that, we
have to finalize the interface and design to make sure that the changes
will work throughout the whole stack (kvm/vfio/qemu/libvirt).
