So:

root@x1:~#
But:
root@x1:~# perf trace perf test -w landlock |& grep landlock_add_rule
26.120 ( 0.002 ms): perf/19791 landlock_add_rule(ruleset_fd: 11, rule_type: LANDLOCK_RULE_PATH_BENEATH, rule_attr: 0x7ffde75e2680, flags: 45) = -1 EINVAL (Invalid argument)
26.124 ( 0.001 ms): perf/19791 landlock_add_rule(ruleset_fd: 11, rule_type: LANDLOCK_RULE_NET_PORT, rule_attr: 0x7ffde75e2690, flags: 45) = -1 EINVAL (Invalid argument)
root@x1:~#

Something in the changes made to:
