Thanks for the help everyone. I did skim SubmittingPatches prior to submission, but dropped off before sections 12 and 15; the information seemed outdated since it made no mention of git by the time I stopped reading (around section 9 or so), so I looked elsewhere. I will resubmit according to the information in Section 15. Do I need to add something like "try 2" to the patch's subject line, or is it okay without that? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
