Where do you store the CRCs? It appears that they are written to another
block device. Also, how do you initialize the CRC table for an existing

What would make this considerably more useful is to be able to write the
CRCs into a regular file, as it would be a bit of a pain to have a partition
for each CRC loop device to store the CRCs in.

Otherwise, it looks very useful, and could be handy in tracking down
reports like this where it is unclear where the data corruption is.
