This will be frequently dumped right now with mm-unstable. Is that what it wanted to achieve?

[ 10.822575] memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=491 'systemd' [ 10.824743] memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=495 '(sd-executor)' ...

If there's already a sane default value (and also knobs for the user to change the default) not sure whether it's saner to just keep it silent as before?
