From 25602c97f50e4b7fea84d2c81326dc5e372ca868 Mon Sep 17 00:00:00 2001 From: Jayamohan Kallickal Date: Mon, 22 Aug 2011 10:08:28 -0700 Subject: [PATCH] [SCSI] be2iscsi: Adding a shutdown Routine This patch adds a shutdown routine. It fixes a bug where when be2net and be2iscsi are both used be2iscsi was not cleaning up its resources properly causing be2net to fail to get loaded when the system is rebooted.
