From 78bc3334a69ff289dbc973a9db7c52a2d7757e5b Mon Sep 17 00:00:00 2001 From: Jiang Biao Date: Wed, 24 Apr 2019 08:58:57 +0800 Subject: [PATCH] fs/quota: erase unused but set variable warning 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().
