Until we see the change, we can't say their is interest in merging the change HEAD, let alone 2.1.
Here's what I've submitted so far:
If desired I could provide patches against 2.1.22 as well.
No point in that just yet. Better to wait until after the patch (with or without changes) has been accepted into HEAD. Then, depending on issue being addressed, a determination will be made whether to backport to 2.1 and how. In most cases the backport is done by the release engineer.
