Hi

I discussed it with Milan Broz <gmazyland@...il.com> and we concluded that 
there is no need to bloat dm-crypt with this logic.

We believe that you should create your own target (like 
"dm-inline-crypt"), it would work like a linear target and it will attach 
encryption requests to the bios that it processes.
