OK, I have added this to the end of linux-next today (in the part of Andrew's tree afte the linux-next merge). I also move the fortify string patch to after it (but I assume I will still need to revert it). I willl drop this patch when it appears elsewhere in linux-next. -- Cheers, Stephen Rothwell
