[people/pmueller/ipfire-2.x.git] / src / patches / suse-2.6.27.31 / patches.arch / s390-04-01-qdio_prevent_double_shutdown.patch

From: Gerald Schaefer <geraldsc@de.ibm.com>
Subject: qdio: prevent double qdio shutdown in case of I/O errors.
References: bnc#445100

Symptom:     I/O errors reported using a zfcp disk.
Problem:     In case of I/O errors on a qdio subchannel qdio_shutdown may be 
             called twice by the qdio driver and by zfcp. 
Solution:    Remove the superfluous shutdown from qdio and let the upper layer driver
             handle the error condition.
