From 4149268e7816d719b0fde8e89aaa6db8c168fc43 Mon Sep 17 00:00:00 2001 From: Joern Engel Date: Fri, 18 May 2012 13:57:19 -0700 Subject: target: Add TFO->put_session() caller for HW fabric session shutdown This patch adds an optional target_core_fabric_ops->put_session() caller within the existing target_put_session() code path. This is required by tcm_qla2xxx code in order to invoke it's own fabric specific session shutdown handler using se_session->sess_kref.
