The fprobe test fails on Fedora 41 since the fprobe test assumption that
the number of enabled_functions is zero before the test starts is not
necessarily true. Some user space tools, like systemd, add BPF programs
that attach to functions. Those will show up in the enabled_functions table
and must be taken into account by the fprobe test.

Hmm, this ftrace selftests has been expected to be run without 
any BPF programs... Is there any other issue on other test cases?

At least on s390 all tests pass now.

That is of course except for the "add/remove/test uprobe events" test
where I sent a patch. Not sure what will happen with that one:
