Thanks for the summary.  It looks good to me.

Something else to keep mind is the potential to reuse IV generators.

Recently a patch has been proposed for fscrypt that also makes
use of essiv (search for "fscrypt: Add support for AES-128-CBC").
It would be great if we could reuse the same code for both dm-crypt
and fscrypt.

Cheers,
