212 * Jens Axboe <axboe@image.dk>
213 * Chris Zwilling <chris@cloudnet.com>
214 *
215 * 4.51 Dec 23, 1998 -- Jens Axboe <axboe@image.dk>
216 * - ide_cdrom_reset enabled since the ide subsystem
217 * handles resets fine now. <axboe@image.dk>
218 * - Transfer size fix for Samsung CD-ROMs, thanks to
219 * "Ville Hallik" <ville.hallik@mail.ee>.

224 *
225 * 4.53 Feb 22, 1999 - Include other model Samsung and one Goldstar
226 * drive in transfer size limit.
227 * - Fix the I/O error when doing eject without a medium
228 * loaded on some drives.
229 * - CDROMREADMODE2 is now implemented through
230 * CDROMREADRAW, since many drives don't support
231 * MODE2 (even though ATAPI 2.6 says they must).
232 * - Added ignore parameter to ide-cd (as a module), eg
233 * insmod ide-cd ignore='hda hdb'
234 * Useful when using ide-cd in conjunction with
235 * ide-scsi. TODO: non-modular way of doing the
236 * same.
237 *
238 * 4.54 Aug 5, 1999 - Support for MMC2 class commands through the generic
239 * packet interface to cdrom.c.
240 * - Unified audio ioctl support, most of it.
241 * - cleaned up various deprecated verify_area().
242 * - Added ide_cdrom_packet() as the interface for
243 * the Uniform generic_packet().
244 * - bunch of other stuff, will fill in logs later.
245 * - report 1 slot for non-changers, like the other
246 * cd-rom drivers. don't report select disc for
247 * non-changers as well.
248 * - mask out audio playing, if the device can't do it.
249 *
250 * 4.55 Sep 1, 1999 - Eliminated the rest of the audio ioctls, except
251 * for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers
252 * use this independently of the actual audio handling.
253 * They will disappear later when I get the time to
254 * do it cleanly.
255 * - Minimize the TOC reading - only do it when we
256 * know a media change has occurred.
257 * - Moved all the CDROMREADx ioctls to the Uniform layer.
258 * - Heiko Eißfeldt <heiko@colossus.escape.de> supplied
259 * some fixes for CDI.
260 * - CD-ROM leaving door locked fix from Andries
261 * Brouwer <Andries.Brouwer@cwi.nl>
262 * - Erik Andersen <andersen@xmission.com> unified
263 * commands across the various drivers and how
264 * sense errors are handled.
265 *
266 * 4.56 Sep 12, 1999 - Removed changer support - it is now in the
267 * Uniform layer.
268 * - Added partition based multisession handling.
269 * - Mode sense and mode select moved to the
270 * Uniform layer.
271 * - Fixed a problem with WPI CDS-32X drive - it
272 * failed the capabilities
273 *
274 * 4.57 Apr 7, 2000 - Fixed sense reporting.
275 * - Fixed possible oops in ide_cdrom_get_last_session()
276 * - Fix locking mania and make ide_cdrom_reset relock
277 * - Stop spewing errors to log when magicdev polls with
278 * TEST_UNIT_READY on some drives.
279 * - Various fixes from Tobias Ringstrom:
280 * tray if it was locked prior to the reset.
281 * - cdrom_read_capacity returns one frame too little.
282 * - Fix real capacity reporting.
283 *
284 * 4.58 May 1, 2000 - Clean up ACER50 stuff.
285 * - Fix small problem with ide_cdrom_capacity
286 *
287 * 4.59 Aug 11, 2000 - Fix changer problem in cdrom_read_toc, we weren't
288 * correctly sensing a disc change.
289 * - Rearranged some code
290 * - Use extended sense on drives that support it for
291 * correctly reporting tray status -- from
292 * Michael D Johnson <johnsom@orst.edu>

294 * - Bump timeout for packet commands, matches sr
295 * - Odd stuff
