Local variable *reserved* of remove_dquot_ref() is only used if define CONFIG_QUOTA_DEBUG, but not ebraced in CONFIG_QUOTA_DEBUG macro, which leads to unused-but-set-variable warning when compiling. This patch ebrace it into CONFIG_QUOTA_DEBUG macro like what is done in add_dquot_ref(). Signed-off-by: Jiang Biao <benbjiang@tencent.com> Signed-off-by: Jan Kara <jack@suse.cz>
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.
