I didn't say that.

I say that users will misunderstand this taint. Like all the other things we
have issued wrt RAS - people jump to conclusions without even reading english
text. Not to even talk about taint flags.

You having to explain it here basically proves my point.

Thousands huh? I know of only two but maybe you will enlighten me.

And those I know can simply dump you an error log which you can check. It is
way easy already.

Documentation/admin-guide/kdump/vmcoreinfo.rst could be one place.

But again, this is redundant info which you can read out from logs which you
already *have* to collect anyway, in a large fleet.

IMO, you have everything already and this is not really needed.
