Subject: [PATCH 1/6] nvme: add preferred I/O size fields to struct nvme_id_ns_nvm
Date: Thu, 19 Feb 2026 20:28:04 -0700 [thread overview]
Message-ID: <20260220032809.758089-2-csander@purestorage.com> (raw)
In-Reply-To: <20260220032809.758089-1-csander@purestorage.com>
A subsequent change will use the NPDGL and NPDAL fields of the NVM
Command Set Specific Identify Namespace structure, so add them (and the
handful of intervening fields) to struct nvme_id_ns_nvm.
