From 30c7ca9350048486ab32fdb9f5f6ed0603bba39a Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Fri, 23 Nov 2018 18:36:12 +0100 Subject: scsi: target: drop unnecessary get_fabric_name() accessor from fabric_ops All fabrics return a const string. In all cases *except* iSCSI the get_fabric_name() string matches fabric_ops.name. Both fabric_ops.get_fabric_name() and fabric_ops.name are user-facing, with the former being used for PR/ALUA state and the latter for ConfigFS (config/target/$name), so we unfortunately need to keep both strings around for now. Replace the useless .get_fabric_name() accessor function with a const string fabric_name member variable. Signed-off-by: David Disseldorp Reviewed-by: Christoph Hellwig Signed-off-by: Martin K.
