Can you clarify a little with regard to how you'd have liked this
patchset to look? With
https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/commit/?h=usercopy-v4.15-rc1&id=93edfb33387772a9ae7693ddf9811280ffc4025b
it seems pretty like we're at the end goal you've described (default to
a mode that generates a warning rather than returning an error), so is
it just that this appeared at the end of the patchset development
process rather than being there from the beginning?
