Subject: [PATCH 3/5] libnvdimm, label: return nd_label directly instead of calculating it again
Date: Mon, 28 Jan 2019 08:30:16 +0800 [thread overview]
Message-ID: <20190128003018.4087-3-richardw.yang@linux.intel.com> (raw)
In-Reply-To: <20190128003018.4087-1-richardw.yang@linux.intel.com>
In nd_label_active(), we get nd_label from label area. While it is not
necessary to calculate it a second time.
This patch return nd_label directly.
