I'm not sure it is the right decision. Right. However you can't force the user to give you data that's always layed out in blocks. For example, an IP fragment might give you an sg element that's only half an AES block. You should either use the blkcipher walking helpers to avoid this or do your own copying when you detect that you have a partial block in an sg element. Also, the MAY_BACKLOG option must be implemented or dm-crypt won't work properly.
