For each dquot resource, ensure either (a) the resource usage is over the soft limit and there is a nonzero timer; or (b) usage is at or under the soft limit and the timer is unset. (a) is redundant with the dquot buffer verifier, but (b) isn't checked anywhere. Found by fuzzing xfs/426 and noticing that diskdq.btimer = add didn't trip any kind of warning for having a timer set even with no limits. 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.
