Hi Steven,
If I execute test.d/00basic/test_ownership.tc in a row,
it passes in the first run, and fails in the second run.
I observe this on the Ubuntu 24.04 (6.8 kernel),
and also on the latest linux-next (next-20240520).
Is this a limitation of the test or a kernel bug?
vagrant@debian:~/linux/tools/testing/selftests/ftrace$ sudo
/ftracetest test.d/00basic/test_ownership.tc

Hmm, that should have been fixed with this pull request:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e92b99ae8216dec2566711dae0a9b7b47591e315
Let me know if you have that, and if so, please send me your config.
Oh, and make sure that you have the latest selftests running too.
Thanks,

Yes, I do.

Sure, attached.

I used the kselftest in the latest tree.
