Valve just recently released proton 4.11 that features new fsnyc for improved multi-threaded gaming, which requires patches for the kernel to work

What exactly is the purpose of this report? Are you asking us to include the
patch set in openSUSE kernel?

Looking at the upstream discussion (third link in the initial comment), I can
see that

(1) The patch set has been submitted as "RFC", i.e. rather initial "What do you
    think about this?", not an official submission meant to be merged as is.
(2) There were nontrivial objections to this version.

I would say including the patch set in openSUSE kernel at this point would be
rather premature.

Agreed, you need to wait for this to hit upstream. And then, it will hit tumbleweed in a couple of weeks.
