In loop_transfer_bio the initial vector has been computed only once. For any situation where more than one bio_vec is present the initial vector will be wrong. Here is the trivial but important fix.
This will fix the disk corruption problems of cryptoloop for block-backed loop devices mentioned earlier this month on this list.
This should close http://bugme.osdl.org/show_bug.cgi?id=1000
Please confirm.
