From ac61e869bef13a43d624893559acbac3a4e2a341 Mon Sep 17 00:00:00 2001 From: Caleb Sander Mateos Date: Fri, 27 Feb 2026 13:23:46 -0700 Subject: nvme: add preferred I/O size fields to struct nvme_id_ns_nvm 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. Add an assertion that the size is still 4 KB.
