From: Joe Thornber Fix a harmless typo. The root is a chunk of data that gets written to the superblock. This data is used to recreate the space map when opening a metadata area. We have two space maps; one tracking space on the metadata device and one of the data device. Both of these use the same format for their root, so this typo was harmless.
