AFAICT this never worked, as it seems I did the rework in SMD while we
tried to figure out the dependency issues we had with moving to SMD. So
v4.9 through v4.11 has SMD support - with this bug.

How do I proceed, do you want me to write up a fix for stable@? Do I
send that out as an ordinary patch?

If the patch applies cleanly on branches linux-4.9.y through linux-4.11.y in
the stable repository you can go for '--- Option 1 ---' as described in
<linux-repo>/Documentation/stable_kernel_rules.txt.

It does not, before v4.12 it's a completely different function to call
to close the channel.

But "Option 3" describes the situation, thanks for the reference. I'll
try to find the time to verify the patch on v4.11 and send it to
stable@.

Great, thanks. This seems to be that serious that better to fix this
also in older releases.
