And what kernels have you tested this on?  How far back should it go?

For mm patches like this, that are not explicitly tagged by the
maintainers to be included in the stable tree, we need their ack to be
able to apply them based on their requests.  So can you get that for
this change and provide tested patches, we will be glad to queue them
up.

thanks,
