-From: Gerald Schaefer <geraldsc@de.ibm.com>
-Subject: zfcp: Fix port reference counting
-References: bnc#487755,LTC#52847
-
-Symptom:     If this problem appears zfcp ports cannot
-             be de-queued since it is checked for a
-             zero refcount.
-Problem:     The port reference counting is wrong for
-             existing zfcp ports when e.g. an adapter
-             gets on-line again.
-Solution:    During port scanning the reference counting
-             for existing ports should not be changed.
