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. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
