From a5b1cd61820e88d90454ad87154856a7a20aafbf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 4 Mar 2024 07:04:52 -0700 Subject: nvme: move a few things out of nvme_update_disk_info Move setting up the integrity profile and setting the disk capacity out of nvme_update_disk_info to get nvme_update_disk_info into a shape where it just sets queue_limits eventually.
