29 -- Initial version by David A. van Leeuwen. I don't have a detailed
32 2.00 Dec 2, 1997 -- Erik Andersen <andersee@debian.org>
33 -- New maintainer! As David A. van Leeuwen has been too busy to actively
37 -- Added (rudimentary) sysctl interface. I realize this is really weak
40 -- Modified CDROM_DISC_STATUS so that it is now incorporated into
41 the Uniform CD-ROM driver via the cdrom_count_tracks function.
46 -- Remove the calls to verify_area and only use the copy_from_user and
50 -- Major update to return codes so that errors from low-level drivers
54 -- Made it so if a function isn't implemented in a low-level driver,
57 -- Simplified some complex logic so that the source code is easier to read.
59 -- Other stuff I probably forgot to mention (lots of changes).
61 2.01 to 2.11 Dec 1997-Jan 1998
62 -- TO-DO! Write changelogs for 2.01 to 2.12.

76 -- Fixed it so that the /proc entry now also shows up when cdrom is
79 2.14 August 17, 1998 -- Erik Andersen <andersee@debian.org>
80 -- Fixed a bug in cdrom_media_changed and handling of reporting that
83 -- Made a few things more pedanticly correct.
85 2.50 Oct 19, 1998 - Jens Axboe <axboe@image.dk>
86 -- New maintainers! Erik was too busy to continue the work on the driver,

96 -- Fixed an error in open_for_data where we would sometimes not return
98 -- Fixed module usage count - usage was based on /proc/sys/dev
100 modules had entries in dev. Feb 02 - real bug was in sysctl.c where
104 2.53 Feb 22, 1999 - Jens Axboe <axboe@image.dk>
105 -- Fixup of several ioctl calls, in particular CDROM_SET_OPTIONS has
108 -- Added CDROM_LOCKDOOR ioctl. Locks the door and keeps it that way.
109 -- Added CDROM_RESET ioctl.
110 -- Added CDROM_DEBUG ioctl. Enable debug messages on-the-fly.
111 -- Added CDROM_GET_CAPABILITY ioctl. This relieves userspace programs
114 2.54 Mar 15, 1999 - Jens Axboe <axboe@image.dk>
115 -- Check capability mask from low level driver when counting tracks as
118 2.55 Apr 25, 1999 - Jens Axboe <axboe@image.dk>
119 -- autoclose was mistakenly checked against CDC_OPEN_TRAY instead of
121 -- proc info didn't mask against capabilities mask.
123 3.00 Aug 5, 1999 - Jens Axboe <axboe@image.dk>
124 -- Unified audio ioctl handling across CD-ROM drivers. A lot of the
127 -- First attempt at adding support for MMC2 commands - for DVD and
128 CD-R(W) drives. Only the DVD parts are in now - the interface used is
130 -- ioctl cleanups. if a drive couldn't play audio, it didn't get
132 -- Defined CDROM_CAN(CDC_XXX) for checking the capabilities.
133 -- Put in sysctl files for autoclose, autoeject, check_media, debug,
135 -- /proc/sys/dev/cdrom/info has been updated to also contain info about
136 CD-Rx and DVD capabilities.
137 -- Now default to checking media type.
138 -- CDROM_SEND_PACKET ioctl added. The infrastructure was in place for

153 DVD patches for ide-cd and while I rearranged and unified them, the
156 3.03 Sep 1, 1999 - Jens Axboe <axboe@image.dk>
157 -- Moved the rest of the audio ioctls from the CD-ROM drivers here. Only
159 -- Moved the CDROMREADxxx ioctls in here.
160 -- Defined the cdrom_get_last_written and cdrom_get_next_block as ioctls

170 -- Integrated Uniform CD Changer handling from Richard Sharman
172 -- Defined CD_DVD and CD_CHANGER log levels.
173 -- Fixed the CDROMREADxxx ioctls.
174 -- CDROMPLAYTRKIND uses the GPCMD_PLAY_AUDIO_MSF command - too few
176 -- Small modifications to accommodate opens of /dev/hdc1, required
177 for ide-cd to handle multisession discs.
178 -- Export cdrom_mode_sense and cdrom_mode_select.
179 -- init_cdrom_command() for setting up a cgc command.
181 3.05 Oct 24, 1999 - Jens Axboe <axboe@image.dk>
