This specific patch didn't change. The change is only in [patch v3
3/6] (crash fix) and in [patch v3 6/6] (new patch that add stats).

Do you mean I should use --annotate to git send-email to specify what
has changed across versions for each patch? I used --compose and put
what changed from v2 to v3 in the introductory message [patch 0/6].

I got a message saying a test failed on [patch 3/5]. I resubmitted the
entire thread because I wasn't sure if you would drop the failing
patch set. If the entire failing patch set is dropped, then v3 can be
used as a replacement.

If you prefer a fixup patch, I can post another patch set (the crash
fix and the new patch) on top of what you already applied, but it
might be easier to do what's described in the previous paragraph (drop
v2 and apply v3).
