This states what the patch does, but not why.
The description you put in the cover letter does capture the why, but
the cover-letter won't be part of the git history (and if it was,
there's no reason to keep the motivation separate from the change). So
please move the motivation into the commit message.
Also, there's generally no reason to have a cover-letter for a
single patch "series". So please skip the --cover-letter.
