What happened to a patch fixing this? Did I miss it? Was it submitted
independently to the net tree?

Ditto.
I don't think these need to be fixed in the net tree, but it would still
be nice to fix the problem. Please do so, as an initial patch in your
series - so we can then backport if it turns out to eventually be
necessary.
Thanks.
