I like this. Nice and clean.
May I assume that this is -not- intended as a replacement for
cryptoloop? I hope so, as that would be my recommendation: new driver,
new on-disk format.
cryptoloop predates block layer stacking, and also support files, so I
would prefer to emphasize their differences. A replacement for
cryptoloop means you must support cryptoloop's on-disk format.
