I think there was a misunderstanding. I asked you to queue the
commit with that ID to stable on Dec 23 (this commit ID is the
revert of the buggy patch). This commit was included to stable
on Jan 4 then:

https://www.spinics.net/lists/stable/msg208727.html

So with this, everything was ok.

Maybe you started to look again into this because Nicolas Dichtel
(Cced) asked to queue this patch on Jan 5, the patch was already
in the stable tree (Jan 4) but probably not in an actual release
at this time.

I think we can we can just drop this.

Unless Nicolas knows something that is still missing, v4.14.12 and
above should be ok as is.
