-From: Gerald Schaefer <geraldsc@de.ibm.com>
-Subject: Fix zfcp problems that have been found
-References: bnc#434333
-
-Symptom:     lock dependency warnings and flaws found during code review
-Problem:     various small zfcp problems
-Solution:    fix zfcp problems
-                - SCSI command times out on "deleted scsi device"
-                - fix memory leak for status_read requests
-                - locking for req_list
-                - fix error path for failed request send
