+Subject: [PATCH 1/3] fsinfo: Introduce a non-repeating system-unique
+ superblock ID
+
+Introduce an (effectively) non-repeating system-unique superblock ID that
+can be used to determine that two objects are in the same superblock
+without needing to worry about the ID changing in the meantime (as is
+possible with device IDs).
+
+The counter could also be used to tag other features, such as mount
+objects.
