This patchset looks strange. There seems to be 15 patches, but there are
30 e-mails in the thread? You can also see this when you look at it in
lore [1]. And they are different repeated e-mails (mutt does not
de-duplicate them). Also `b4 shazam ...` does not work. What happened?
Did you send it twice with the same mail ID? Am I the only one seeing
this?

I would suggest the following (hopefully you are using b4):
1. Check to see how things will be sent with b4. `b4 send --resend -o OUTPUT_DIR`
   If you see 30 emails in that dir from your patchset then something is
   still wrong.
2. After you make sure that everything is in order. Do the resend
   without bumping the version up (leave it at version 4)

Best
