Hi

I'd recommend  to exec "dmsetup"  call - as that's by far the simplest 
solution for your problem.

Verity tool should supposedly solve 'compatibility' between various versions 
and various capabilities of driver.

What is the idea behind redevelopment of this tool by your  C code  (as 
clearly you should then do the same thing as verity tool)  ?
