Subject: [PATCH 2/3] nvme/multipath: cosmetic: keep ns nsid locally
Date: Sat, 11 Sep 2021 19:07:30 -0600 [thread overview]
Message-ID: <20210912010731.471859-3-anton@lightbitslabs.com> (raw)
In-Reply-To: <20210912010731.471859-1-anton@lightbitslabs.com>
Keep the nsid of the current namespace in a local variable.
Change the type to unsigned int to make checkpatch happy.
