Please always say that you modified the code from the original version, and _why_ you did such a modification. Otherwise I'll assume you did this backport wrong and throw it out. Like I'm doing now :) Please fix up and resend all of the remaining of the series you wish to see added to 3.14-stable. thanks, gre 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
