From 3beeabd5f2d1fc7a48cb887a298bc412789a1f68 Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Wed, 5 Dec 2018 13:18:38 +0100 Subject: [PATCH] scsi: target: perform t10_wwn ID initialisation in target_alloc_device() Initialise the t10_wwn vendor, model and revision defaults when a device is allocated instead of when it's enabled. This ensures that custom vendor or model strings set prior to enablement are not later overwritten with default values. The TRANSPORT_FLAG_PASSTHROUGH conditional can be dropped for the following reasons: - target_core_pscsi overwrites the defaults in the pscsi_configure_device() callback. + the contents is then only used for ConfigFS via $pscsi_dev/statistics/scsi_lu/vend, etc. - target_core_user doesn't touch the defaults, nor are they used for anything outside of ConfigFS.
