Darrick J. Wong 45068063ef xfs: fix incorrect root dquot corruption error when switching group/project quota types 
While writing up a regression test for broken behavior when a chprojid
request fails, I noticed that we were logging corruption notices about
the root dquot of the group/project quota file at mount time when
testing V4 filesystems.

In commit afeda6000b, I was trying to improve ondisk dquot validation
by making sure that when we load an ondisk dquot into memory on behalf
of an incore dquot, the dquot id and type matches.  Unfortunately, I
forgot that V4 filesystems only have two quota files, and can switch
that file between group and project quota types at mount time.  When we
perform that switch, we'll try to load the default quota limits from the
root dquot prior to running quotacheck and log a corruption error when
the types don't match.

This is inconsequential because quotacheck will reset the second quota
file as part of doing the switch, but we shouldn't leave scary messages
in the kernel log.

Fixes: afeda6000b ("xfs: validate ondisk/incore dquot flags")

README 

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.
