Subject: [PATCH 2/3] nvme-pci: disable namespace identifiers for the MAXIO MAP1002/1202
Date: Wed, 13 Apr 2022 06:49:04 +0200	[thread overview]
Message-ID: <20220413044905.376785-3-hch@lst.de> (raw)
In-Reply-To: <20220413044905.376785-1-hch@lst.de>

The MAXIO MAP1002/1202 controllers reports completely bogus Namespace
identifiers that even change after suspend cycles.  Disable using
the Identifiers entirely.
