Those are all lofty goals but beware that trying to solve it all at
once can be very painful and can cause unnecessary work for both coders
and reviewers. Especially if the patchset grows out of proportion which
makes it much harder to review and deal with.

So, from my experience and if I were you, I'd try to address the most
important issue I'm trying to fix, have 10ish nice clean patches and put
the rest on the TODO list. This is much easier to deal with for everyone
involved than trying to solve it all at once.

Besides, if you solve it all at once, what are you going to work on
afterwards? :-)

HTH.
