It's also only a measure of how much of the tuneable memory usage it
should aim for, but OSDs also have a separate need for ram that is not
negotiable (often at startup and recovery) and for that usage,
preferences are not applied, it will try to use the ram it needs in
order to fix itself regardless of the admins preferences.
