Sorry for the late reply. I've been hacking on other things and my queue of stuff for tip still hasn't been pulled yet. I'll pull this into my tree, and see if I can get it in by the merge window. If the merge window opens this weekend, I'll add this to my 3.9 queue. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
