Bug#550898: DASD DIAG driver doesn't work for read-only minidisks (s390, s390x only)

[Stephen Powell <zlinuxman@wowway.com>]

An official fix has now been published for this problem by upstream
development for kernel 2.6.33.  See

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=22825ab7693fd29769518a0d25ba43c01a50092a

Please consider backporting it to 2.6.32 so that when Squeeze freezes, this fix will be included.
Also please consider backporting it to 2.6.26 (Lenny) in the next stable point release
or in a security update.  Suse considered this fix important enough to backport it to
2.6.27 (SLES11) and 2.6.16 (SLES10).  (See http://lists.debian.org/debian-s390/2009/12/msg00013.html)

For the security argument, please see http://lists.debian.org/debian-s390/2009/12/msg00025.html.
This posting also contains a link to my unofficial backport of the fix to 2.6.26.
As the author, I hereby grant permission to anyone to use it for any purpose whatsoever.
Or, if you prefer, you can do your own backport.

I will try to get upstream to include the patch in one of their "stable updates" for 2.6.32
as well, but it would help if I had some allies at Debian.
