This is getting silly. We've spent three months arguing over shell
scripts and makefiles for what should be a trivial feature.
We make fundamental changes to the VM code with less contention.

It's not helped that timezones are working against everyone here,
so even minor changes end up taking a while to get reposted, re-reviewed
etc, but the level of pushback because something isn't perfect is absurd,
especially when we're talking about new features.

If you want the in-kernel variant to be perfect every step of the way,
and move slowly and never introduce subtle breakage along the way that then
gets fixed up in subsequent changes, maybe a faster moving external project
that syncs up with the kernel tree is the way forward.

If kselftests is going to evolve into something useful, something has to change.
