Yeah, I could have explained some parts of the patch more.
I will try to do better.

Great commit message indeed! Though I fear that such long messages (for a
not very long patch) could take precious screen real estate when using "git

Anyway do you want me to resend the patch or the series with improved commit
messages ?
