This series uses the inode scanner and live update hook functionality introduced in the last patchset to implement quotacheck on a live filesystem. The quotacheck scrubber builds an incore copy of the dquot resource usage counters and compares it to the live dquots to report discrepancies. If the user chooses to repair the quota counters, the repair function visits each incore dquot to update the counts from the live information. The live update hooks are key to keeping the incore copy up to date. This has been running on the djcloud for months with no problems. Enjoy! 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 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.
