Hi,

You seem to have some issues with your mailer that mangles the mail, you
should try using git-send-email instead.

There's also a bunch of checkpatch --strict issues you want to get rid
of.

Instead of a URL that might be dead at some point, it would be better to
have a proper commit log explaining why you did your patch that way
