Subject: [PATCH v2 0/3] perf probe: Allow names to start with digits

This is a rebase of the patch orginally sent almost two years ago here:
https://lkml.kernel.org/r/20220612061508.1449636-1-asmadeus@codewreck.org

At the time I was asked to add tests, and Jiri whipped up something to
make the test pass even for probes that don't exist on most systems but
that ended up never being formatted or sent... I asked what happened of
it and got asked to send it myself, but obviously also totally forget
about it myself until I needed it again now.

I've taken the diff from that thread, adapted it a little bit to the
current master branch and checked things still fall in place -- I didn't
see any obvious problem.

Thanks!

- (not a change, but after being brain-dead and Ian helpful
reply I'm confirming patch 3/3 works as expected)
- Link to v1: https://lore.kernel.org/r/20240407-perf_digit-v1-0-57ec37c63394@codewreck.org
