For one or two simple fix-ups in the set perhaps, but when submitting
the entire set it needs to be threaded as a separate block, rather
than seeing current and superseded patches inter-woven. This
submission is already a rat's nest and I'm struggling to see which
patches are which. I'm really not looking forward to v3 and v4!
Attaching one version to another is a good way to keep control if you
really are over-whelmed. For your use-case I would expect to see the
following, which is achieved using --in-reply-to:
[PATCH 0/2] Here is what I did...
[PATCH 1/2] Clean up and tests
[PATCH 2/2] Implementation
[PATCH v2 0/3] Here is a reroll
[PATCH v2 1/3] Clean up
[PATCH v2 2/3] New tests
[PATCH v2 3/3] Implementation
The version numbers also need to be present and aren't in this
re-submission.

For all commits? Then I'm guessing your Git history is all but
unreadable. In the kernel, unless the changelog holds valuable
historic information which influance key design decisions, we put the
patch changelog *below* the '---'.
Please read Documentation/SubmittingPatches:
"14) The canonical patch format
[...]
The "---" marker line serves the essential purpose of marking
for patch handling tools where the changelog message ends.
[...]
Other comments relevant only to the moment or the maintainer,
not suitable for the permanent changelog, should also go here.
A good example of such comments might be *"patch changelogs"*
which describe what has changed between the v1 and v2 version
of the patch."
