- *
- * ----------------------------------

- * by Toni Giorgino <toni@pcape2.pi.infn.it>, the SCSI
- * version, and my own efforts. -erik
- * -- Fixed a stupid bug which egcs was kind enough to
- * inform me of where "Illegal mode for this track"
- * was never returned due to a comparison on data
- * types of limited range.
- * 4.12 Mar 29, 1998 -- Fixed bug in CDROM_SELECT_SPEED so write speed is
- * now set ionly for CD-R and CD-RW drives. I had

- * handles resets fine now. <axboe@image.dk>
- * - Transfer size fix for Samsung CD-ROMs, thanks to
- * "Ville Hallik" <ville.hallik@mail.ee>.
- * - other minor stuff.
- *
- * 4.52 Jan 19, 1999 -- Jens Axboe <axboe@image.dk>
- * - Detect DVD-ROM/RAM drives
- *
- * 4.53 Feb 22, 1999 - Include other model Samsung and one Goldstar
- * drive in transfer size limit.
- * - Fix the I/O error when doing eject without a medium
- * loaded on some drives.
- * - CDROMREADMODE2 is now implemented through
- * CDROMREADRAW, since many drives don't support
- * MODE2 (even though ATAPI 2.6 says they must).
- * - Added ignore parameter to ide-cd (as a module), eg
- * insmod ide-cd ignore='hda hdb'
- * Useful when using ide-cd in conjunction with
- * ide-scsi. TODO: non-modular way of doing the
- * same.
- *
- * 4.54 Aug 5, 1999 - Support for MMC2 class commands through the generic
- * packet interface to cdrom.c.
- * - Unified audio ioctl support, most of it.
- * - cleaned up various deprecated verify_area().
- * - Added ide_cdrom_packet() as the interface for
- * the Uniform generic_packet().
- * - bunch of other stuff, will fill in logs later.
- * - report 1 slot for non-changers, like the other
- * cd-rom drivers. don't report select disc for
- * non-changers as well.
- * - mask out audio playing, if the device can't do it.
- *
- * 4.55 Sep 1, 1999 - Eliminated the rest of the audio ioctls, except
- * for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers
- * use this independently of the actual audio handling.
- * They will disappear later when I get the time to
- * do it cleanly.
- * - Minimize the TOC reading - only do it when we
- * know a media change has occurred.
- * - Moved all the CDROMREADx ioctls to the Uniform layer.
- * - Heiko Eißfeldt <heiko@colossus.escape.de> supplied
- * some fixes for CDI.
- * - CD-ROM leaving door locked fix from Andries
- * Brouwer <Andries.Brouwer@cwi.nl>
- * - Erik Andersen <andersen@xmission.com> unified
- * commands across the various drivers and how
- * sense errors are handled.
- *
- * 4.56 Sep 12, 1999 - Removed changer support - it is now in the
- * Uniform layer.
- * - Added partition based multisession handling.
- * - Mode sense and mode select moved to the
- * Uniform layer.
- * - Fixed a problem with WPI CDS-32X drive - it
- * failed the capabilities
- *
- * 4.57 Apr 7, 2000 - Fixed sense reporting.
- * - Fixed possible oops in ide_cdrom_get_last_session()
- * - Fix locking mania and make ide_cdrom_reset relock
- * - Stop spewing errors to log when magicdev polls with
- * TEST_UNIT_READY on some drives.
- * - Various fixes from Tobias Ringstrom:
- * tray if it was locked prior to the reset.
- * - cdrom_read_capacity returns one frame too little.
- * - Fix real capacity reporting.
- *
- * 4.58 May 1, 2000 - Clean up ACER50 stuff.
- * - Fix small problem with ide_cdrom_capacity
- *
- * 4.59 Aug 11, 2000 - Fix changer problem in cdrom_read_toc, we weren't
- * correctly sensing a disc change.
- * - Rearranged some code
- * - Use extended sense on drives that support it for
- * correctly reporting tray status -- from
- * Michael D Johnson <johnsom@orst.edu>
- * 4.60 Dec 17, 2003 - Add mt rainier support
- * - Bump timeout for packet commands, matches sr
- * - Odd stuff
- * 4.61 Jan 22, 2004 - support hardware sector sizes other than 2kB,
- * Pascal Schmidt <der.eremit@email.de>
