From 5a7125c64def3b21f8147eca8b54949a60963942 Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Fri, 22 May 2015 14:07:44 -0700 Subject: target/pscsi: Don't leak scsi_host if hba is VIRTUAL_HOST See https://bugzilla.redhat.com/show_bug.cgi?id=1025672 We need to put() the reference to the scsi host that we got in pscsi_configure_device(). In VIRTUAL_HOST mode it is associated with the dev_virt, not the hba_virt.
