Subject: [PATCH 07/10] nvme: revalidate after verifying identifiers
Date: Thu, 9 Apr 2020 09:09:05 -0700 [thread overview]
Message-ID: <20200409160908.1889471-8-kbusch@kernel.org> (raw)
In-Reply-To: <20200409160908.1889471-1-kbusch@kernel.org>
If the namespace identifiers have changed, skip updating the disk
information, as that will register parameters from a mismatched
namespace.
