* Bugreports.to..: <Linux390@de.ibm.com>
* (C) IBM Corporation, IBM Deutschland Entwicklung GmbH, 1999,2000
*
* $Revision: 1.38 $
*
* History of changes (starts July 2000)
* 07/11/00 Enabled rotational position sensing
* 07/14/00 Reorganized the format process for better ERP
* 07/20/00 added experimental support for 2105 control unit (ESS)
* 07/24/00 increased expiration time and added the missing zero
* 08/07/00 added some bits to define_extent for ESS support
* 09/20/00 added reserve and release ioctls
* 10/04/00 changed RW-CCWS to R/W Key and Data
* 10/10/00 reverted last change according to ESS exploitation
* 10/10/00 now dequeuing init_cqr before freeing *ouch*
* 26/10/00 fixed ITPM20144ASC (problems when accessing a device formatted by VIF)
* 01/23/01 fixed kmalloc statement in dump_sense to be GFP_ATOMIC
* fixed partition handling and HDIO_GETGEO
* 2002/01/04 Created 2.4-2.5 compatibility mode
* 05/04/02 code restructuring.
* $Revision: 1.42 $
