The size is just a value that is passed to the lib. The lib itself wants
the volume size in bytes.

The thing is that you usually don't want to return a fstype, if the
volume is a raid member. Therefore a probe for a filesystem before
looking for a raid can do pretty bad things. But sure, we can change
anything that's reasonable.

Sure, let me know, if I can make anything to fit the needs, or split it out of
the udev tree some day ...

Thanks,
