That would be an argument if this was a new patch series. "Wait a few months".

But that just isn't the case here.

The fact is, these patches have been floating around in one form or
another not for a couple of months, but for years. There's a LWN
article about it from 2015, and it wasn't new back then either (slides
from 2013).

I wouldn't be surprised if there had been academic _papers_ written
about the notion.

So if there *still* is no actual real code around this, then that
just strengthens my point - no way should we merge something where
people haven't actually bothered to write the user-mode component for
years and years.

It really boils down to: "if nobody can be bothered to write the user
