s390/dasd: Make module parameter visible in sysfs

2014-09-01T07:56:28Z

Change the visibility of the dasd parameter of kernel module dasd_mod to be consistent with the eer_pages parameter. Signed-off-by: Peter Oberparleiter Acked-by: Stefan Weinhuber Signed-off-by: Martin Schwidefsky

s390: replace strict_strtoul() with kstrtoul()

2013-08-22T10:20:00Z

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

s390/dasd: Add 'timeout' attribute

2013-07-01T15:31:25Z

This patch adds a 'timeout' attibute to the DASD driver. When set to non-zero, the blk_timeout function will be enabled with the timeout specified in the attribute. Setting 'timeout' to '0' will disable block timeouts. Signed-off-by: Hannes Reinecke Signed-off-by: Stefan Weinhuber Signed-off-by: Martin Schwidefsky

s390/dasd: make number of retries configurable

2013-07-01T15:31:17Z

Instead of having the number of retries hard-coded in the various functions we should be using a default retry value, which can be modified via sysfs. Signed-off-by: Hannes Reinecke Signed-off-by: Stefan Weinhuber Signed-off-by: Martin Schwidefsky

s390/dasd: add safe offline interface

2012-11-30T14:40:44Z

The regular behavior of the DASD device driver when setting a device offline is to return all outstanding I/O as failed. This behavior is different from that of other System z operating systems and may lead to unexpected data loss. Adding an explicit 'safe' offline function will allow customers to use DASDs in the way they expect them to work. Signed-off-by: Stefan Haberland Signed-off-by: Martin Schwidefsky

s390/comments: unify copyright messages and remove file names

2012-07-20T09:15:04Z

Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: Heiko Carstens
