What code do you think that you can re-use in the kernel? It seems
that the features of the virtual block device, dm(4), and its "targets"
may overlap ccd(4), cgd(4), dk(4), and raid(4), but especially raid(4).
Do you think that LVM needs much more help from the kernel than those
devices already provide?
