to the file do not need to be in ordered form but reads from the file
will be ordered in the same way as the actions_avail sysctl.
- It is important to note that the value of ``actions_logged`` does not
- prevent certain actions from being logged when the audit subsystem is
- configured to audit a task. If the action is not found in
- ``actions_logged`` list, the final decision on whether to audit the
- action for that task is ultimately left up to the audit subsystem to
- decide for all seccomp return values other than ``SECCOMP_RET_ALLOW``.
-
The ``allow`` string is not accepted in the ``actions_logged`` sysctl
as it is not possible to log ``SECCOMP_RET_ALLOW`` actions. Attempting
to write ``allow`` to the sysctl will result in an EINVAL being
