Seeing the large number of changes, compared to previous releases gave me a pause on this patch. So I waited a few minutes and there was a problem report quickly. Is there any way you can provide each change in a seperate patch, so we can narrow down the problem patch? (I have a feeling that most of your changes will do a lot of good) Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
