Subject: [PATCH] nvme: associate stripe size quirk with D4512
Date: Wed, 10 Jun 2020 21:38:36 -0600 [thread overview]
Message-ID: <20200611033836.45701-1-david.fugate@linux.intel.com> (raw)
Intel's D4512 dual-port SSD is based on the older Intel P4500 SSDs
whose development predated the NOIOB feature. Based on a customer
request, the D4512's device ID was changed from the P4500s'. This
patch associates D4512's device ID with the stripe size quirk to
improve its performance.
