+Subject: [PATCH] dm: Fix comparing DM RAID member devices UUID
+
+There is no "UUID" property in UDev we must use the "ID_FS_UUID"
+one.
+This comparison works only because most DM RAID members don't have
+UUID so the check is skipped, but it fails for DDF RAID members
+which have a special GUID/UUID in UDev database.
