Hi all, I see patches 1-5 have already made it to Linus' master branch,
but I can't determine the status of this particular patch.

Assuming it's still under consideration, I'd like to attest to the
significantly higher level of user experience improvement it can give
perf users (see RFC below):  Am I taking the right approach here by
assuming this new error message facility is indeed eligible for upstream
acceptance sometime soon?

Thanks,

Kim
