Maybe put in just a little bit more information. E.g.: With this feature all metadata inodes are places in the metadata directory and no sb root metadata except for the metadir itself it left. The RT device is now shared into a number of rtgroups, where 0 rtgroups mean that no RT extents are supported, and the traditional XFS stub RT bitmap and summary inodes don't exist, while a single rtgroup gives roughly identical behavior to the traditional RT setup, just with checksummed and self identifying metadata. For quota the quota options are read from the superblock unless explicitly overridden. Otherwise looks good: Reviewed-by: Christoph Hellwig
