XFS stores quota records and free space bitmap information in files. Add the necessary infrastructure to enable repairing metadata inodes and their forks, and then make it so that we can repair the file metadata for the rtbitmap. Repairing the bitmap contents (and the summary file) is left for subsequent patchsets. We also add the ability to repair file metadata the quota files. As part of these repairs, we also reinitialize the ondisk dquot records as necessary to get the incore dquots working. We can also correct obviously bad dquot record attributes, but we leave checking the resource usage counts for the next patchsets. This has been running on the djcloud for months with no problems.

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 Restructured Text 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.
