From bdd4aad7ff92ae39c2e93c415bb6761cb8b584da Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Tue, 25 May 2021 13:18:07 -0500 Subject: scsi: iscsi: Fix shost->max_id use The iscsi offload drivers are setting the shost->max_id to the max number of sessions they support. The problem is that max_id is not the max number of targets but the highest identifier the targets can have. To use it to limit the number of targets we need to set it to max sessions - 1, or we can end up with a session we might not have preallocated resources for.
