Hi Christoph,
Thanks for the series.  I suggest you pick up Nathan's patch:
https://github.com/ClangBuiltLinux/linux/commit/a37fa82bde58960c5c966a5c1bef8ace6c9d4f34
that removed the configs that were removed in this series from the
various defconfigs.

I think the other thread still has some questions about when it's ok
to remove filesystems. But it's ultimately the maintainers decision.
Let's continue the discussion in the other thread.
