Michal, Sorry for the slow response - my mail filters weren't behaving well at all... For now, lets just drop this patch. I don't have the time to fix it up. A few months ago I did take a look at what it would mean to use make's -j option and it seemed to me that doing so would require completely changing how the coccinelle script works. I would like to see my M= patch set merged though: https://lkml.org/lkml/2011/11/5/94 Thanks, Greg -- 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/
