Subject: [patch 23/52] [PATCH] dasd: remove strings from s390dbf
Date: Fri, 13 Nov 2009 16:08:47 +0100 [thread overview]
Message-ID: <20091113150913.390066682@de.ibm.com> (raw)
In-Reply-To: 20091113150824.351347652@de.ibm.com
[-- Attachment #1: 122-dasd-s390dbf-strings.diff --]
[-- Type: text/plain, Size: 7805 bytes --]
From: Stefan Haberland <stefan.haberland@de.ibm.com>
Remove strings from s390 debugfeature entries that could lead to a
crash when the data is read from dbf because the strings do not exist
any more.
