[Qemu-devel] [PULL 06/20] vhost/scsi: call vhost_dev_cleanup() at unrealize() time

[Paolo Bonzini <pbonzini@redhat.com>]

From: Igor Mammedov <imammedo@redhat.com>

vhost-scsi calls vhost_dev_init() at realize() time
but forgets to call it's counterpart vhost_dev_cleanup()
at unrealize() time.

Calling it should fix leaking of memory table and
mem_sections table in vhost device. And also unregister
vhost's memory listerner to prevent access from
memory core to freed memory.
