As explained in Documentation/SubmittingPatches: (probably a good idea
to re-read that document)

"For these reasons, the "summary" must be no more than 70-75
characters, and it must describe both what the patch changes, as well
as why the patch might be necessary. It is challenging to be both
succinct and descriptive, but that is what a well-written summary
should do."

Your patch subject line should not be longer than 70-75 characters. If
you need to be more extensive, do so in the first paragraph of your
commit log.
