Yeah, there was some back and forth with the code going on: Terry
changed a little, Dan was taking it and reposting, Terry was also
submitting the previous series, Dave reviewed it. So I decided here to
just swap Terry and my SOBs as I was posting the series now and left
the remaining to Dan the way as it will look like when he will apply
the patch, which means updating the SOB chain again. This keeps the
comment for the change he made to the patch.
