my intent is to get Steven's patch into 4.14 stable as it evidently
fixed the particular issue I was seeing, and as Steven said it has
been in upstream since 4.16 so it's not like backporting it will raise
any red flags. I will start another thread on -stable for it.

I would also like to get to the bottom of it. Unfortunately I haven't
got the expertise in this area nor the time to do it yet. Hence the
intent to take a step back and backport Steven's patch to fix the
issue that has resurfaced in our production recently.

No problem.
I just meant that -stable people can be a bit "unconvinced".

The -stable people tried adding this patch back in April, but ended up
getting complaints up the wazoo (
about how this is not -stable material.

So yes, testing/acks welcome :)
