Thanks.
258f669e7e88 was 4 years ago, so I guess a -stable backport isn't really needed.
However, we need to be concerned about causing new regressions, and I don't think you've presented enough information for this to be determined.
So please provide us with a full description of how the smaps_rollup output will be altered by this patch. Quoting example output would be helpful.
