Ideally, I'd like to see the whole series go in through one tree, which is why I CCed Andrew. I can easily produce several dozen more patches like these, but I just included enough examples to motivate patch 1, and I can send more in any order once that one goes in. - Josh Triplett -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
