Didn't see anything unreasonable in this series, so:

One note though, Sam, I can see re-roll count in the subject of the
cover letter, but not in the subject of the patches that follow. Would
you mind using "git format-patche" with --reroll-count (-v) going
forward? It's way easier to figure out the version of a given patch in
a series if you can see that in the header.

Thanks,
