xfs: metadata inode directory trees [v5.5 03/10]
This series delivers a new feature -- metadata inode directories. This
is a separate directory tree (rooted in the superblock) that contains
only inodes that contain filesystem metadata. Different metadata
objects can be looked up with regular paths.
Start by creating xfs_imeta{dir,file}* functions to mediate access to
the metadata directory tree. By the end of this mega series, all
existing metadata inodes (rt+quota) will use this directory tree instead
of the superblock.
Next, define the metadir on-disk format, which consists of marking
inodes with a new iflag that says they're metadata. This prevents
bulkstat and friends from ever getting their hands on fs metadata files.
With a bit of luck, this should all go splendidly.

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.
