Wong Enable the metadata directory feature. With this feature, all metadata inodes are placed in the metadata directory, and the only inumbers in the superblock are the roots of the two directory trees. The RT device is now sharded 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. A single rtgroup gives roughly identical behavior to the traditional RT setup, but now with checksummed and self identifying free space metadata. For quota, the quota options are read from the superblock unless explicitly overridden via mount options. Signed-off-by: Darrick J.
