Its a habit I got into on my previous job where me and a team where doing a lot
of rebases of an intel vendor kernel to track upstream. I think its useful
information to see where there where merge or rebase conflicts. Thats where
screw up's tended to happen and I just got into a habbit of saving the confilct
list.
I'm happy to remove those.

I will certainly try but, other than the smtp send failure dropping the one
patch and dropping the Conflicts list in the backport is there something else I
need to look out for? I "backported" the 4.9.y backport of Jia's patch I think
that may be one thing Thomas was calling out. Is that ok or should I redo that
backport using the original version it first landed in?
