I know this is an old series, but I think you split it for later
versions and there hasn't been a respin of this final part of the series
yet.
When I just told Peter that get_sector_offset() would go away with your
patches, I decided to check whether this was actually true, and found...

...this bug. I think you want to use get_image_offset() now.
This should also be the last caller of get_sector_offset(), so the
function should go away in this commit.
