Subject: [PATCH 1/4] nvme: cleanup __nvme_check_ids
Date: Thu, 24 Feb 2022 20:28:42 +0100	[thread overview]
Message-ID: <20220224192845.1097602-2-hch@lst.de> (raw)
In-Reply-To: <20220224192845.1097602-1-hch@lst.de>

Pass the actual nvme_ns_ids used for the comparison instead of the
ns_head that isn't needed and use a more descriptive function name.
