If you wish to have a patch included in the stable series, please read
Documentation/stable_kernel_rules.txt which state that adding a:
	Cc: stable <stable@...nel.org>
to the signed-off-by: area will cause it to be automagically included
when the patch gets into Linus's tree.  Otherwise it just causes a lot
of extra work for me to dig around and watch out for it in the future.

thanks,
