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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
