I finally got around baking this into a renamed series, that now calls
it "Context Analysis" - here's a preview:
https://git.kernel.org/pub/scm/linux/kernel/git/melver/linux.git/log/?h=ctx-analysis/dev

As for when we should give this v4 another try: I'm 50/50 on sending
this now vs. waiting for final Clang 22 to be released (~March 2026).

Preferences?
