I'll be tagging a release soon. I've got this problem that adding new meta-schema checks like this one requires fixing up all the existing in tree schemas first. So I give some amount of time before adding them to a tagged release. However, I want to start testing new schemas right away. I haven't come up with a better solution short of importing the meta-schema into the kernel tree or separately versioning them. Rob

IMO, having the meta-schema inside the Kernel tree would be better... It took me some time to discover that some problems I had with a past version of this patch series were due to something outside the Kernel tree, at local/lib/python3.9/site-packages. Thanks, Mauro
