OK, patch looks fine now, thanks! But this isn't:

You need to read Documentation/SubmittingPatches for the full story, but
you can't just add signed-off-by; you need an explicit email from the
person saying that ... plus, signoffs should follow the natural
progression of the patch, so if it's your patch, and you send it to me,
I'll add my signoff before I put it in the tree. This has a legal basis
in the DCO (see SubmittinPatches). We're a lot looser on the various
other tags, though.
Anyway, the above is more for future reference; I'll fix it up.
