Ugh, seems like the GitHub UI messes up Firefox's ability to search :(
I see it now, and it makes sense. Linus ended up with cc937dad85aea
which was supposed to never make it upstream.

On the LLVM19 I see this in all outputs:
ar: libLLVM.so.19.0: cannot open shared object file: No such file or directory

But presumably that's harmless, then.
