Yes, please keep the tooling updates separate from the kernel ones,
the way we now for some time have for the perf tooling too.

That said, mentioning the perf tools, I wish the tracing tools would
do a bit more package checking and helpful error messages too, rather
than just fail with

    fatal error: tracefs.h: No such file or directory

when (presumably) libtracefs and friends are needed.

Hmm?
