Subject: [f2fs-dev] [PATCH V3 1/3] fs: Clean up mapping variable
Date: Fri, 29 Nov 2019 08:32:58 -0800 [thread overview]
Message-ID: <20191129163300.14749-2-ira.weiny@intel.com> (raw)
In-Reply-To: <20191129163300.14749-1-ira.weiny@intel.com>
From: Ira Weiny <ira.weiny@intel.com>
The mapping variable is not directly used in these functions. Just
remove the additional variable.
