since there were only 4 commits I fixed them up manually.
But this approach doesn't scale.
We do rebase our trees when we need to fixup or drop patches and
at any given point a number of commits will be committed by me
and another set by Daniel. When we rebase we cannot keep adding
our SOBs to the other person SOBs.
Then comes the next rebase and we get to the point of
double and triple SOBs ?

I think you need to adjust the script to something like:
SOBs by Daniel | Alexei == commit by Daniel | Alexei
in bpf and bpf-next trees.
