Log message:
	Recognise and give preference to md device partitions (blkext major).
	
	We can already detect MD devices internally. But when using MD partitions,
	these have "block extended major" (blkext) assigned (259). Blkext major
	is also used in general, so we need to check whether the original device
	is an MD device actually.
