Seriously?

You are still trying to sell me "Features first - corrrectness
later/never"?

Go and look at the amount of fallout this has caused in the last years.
io-urine is definitely the leader of the pack in my security@...nel.org
inbox.

Vs. the problem at hand. I've failed to catch a major issue with futex
patches in the past and I'm not seeing any reason to rush any of this to
repeat the experience just because.

You know very well that your whatever depends on this series has to wait
until the basics are sorted and there is absolutely no reason that your
so important things have to be rushed into the next merge window.

It surely makes sense to split these things up into independent series,
but _you_ could have done that weeks ago instead of just reposting an
umodified and unreviewed RFC series from Peter and then coming out now
and complaining about the lack of progress.

Sorry no.

Thanks,
