*
- * $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.
