Subject: Re: [PATCH v2 02/10] selftests: liveupdate: Add tests for preserve and retrieve user argument

> Verify the user argument support in LIVEUPDATE_SESSION_PRESERVE_FD and
> LIVEUPDATE_SESSION_RETRIEVE_FD. Add luo_session_preserve_fd_arg() and
> luo_session_retrieve_fd_arg() helpers to libliveupdate so tests can pass
> a handler-specific argument.
>
> Add a preserve_memfd_with_arg test case to verify that memfd
> preservation rejects a non-zero argument with -EOPNOTSUPP, accepts an
> explicit zero argument, and remains compatible with callers passing the
> legacy struct size up to the token field.
