This one is now ok:

     0.004 ( 0.000 ms): perf/200342 landlock_add_rule(ruleset_fd: 11, rule_type: LANDLOCK_RULE_NET_PORT, rule_attr: 0x7ffd649bd0d0, flags: 45) = -1 EINVAL (Invalid argument)
root@number:~# perf test enum
105: perf trace enum augmentation tests                              : Ok
root@number:~#

now looking at:

root@number:~# perf test -vvvvvvvvv 106
106: perf trace BTF general tests:
--- start ---
test child forked, pid 200467
Checking if vmlinux BTF exists
Testing perf trace's string augmentation
String augmentation test failed
---- end(-1) ----
106: perf trace BTF general tests                                    : FAILED!
root@number:~#

No clue from the test, reading its source code now to see where it is
failing to try and reproduce the problem.
