Probably fine, as somebody putting a S-o-b in their subject deserves whatever they get.

I don't think it really matters in practice, but it's an interesting inconsistency. Other than that (and I do not think it is worth re-rolling for this; just an interesting observation), the patch looks OK to me. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
