Jan Kara c3a1f5ba11 quota: Properly disable quotas when add_dquot_ref() fails
[ Upstream commit 6a4e3363792e30177cc3965697e34ddcea8b900b ]

When add_dquot_ref() fails (usually due to IO error or ENOMEM), we want
to disable quotas we are trying to enable. However dquot_disable() call
was passed just the flags we are enabling so in case flags ==
DQUOT_USAGE_ENABLED dquot_disable() call will just fail with EINVAL
instead of properly disabling quotas. Fix the problem by always passing
DQUOT_LIMITS_ENABLED | DQUOT_USAGE_ENABLED to dquot_disable() in this
case.

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.
