But does it slow it down? My machine has horrible build times with this patch installed on 3.14-rc2. Reverted, my builds go back to normal speeds (2 minutes instead of 8 minutes.) I'm going to drop this patch from the stable trees for now, as I can't live with that kind of performance decrease on my machines. sorry, greg k-h -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
