146		were never using.
147	
148		* sd.c: Use restore_flags in do_sd_request - this may result in

153		* st.c: Use bytes, not STP->buffer->buffer_size when reading
154		from tape.

481	
482		Patches from me (ERY) to finish support for low-level loadable scsi.
483		It now works, and is actually useful.
484	
485		* Throughout - add new argument to scsi_init_malloc that takes an
486		additional parameter.  This is used as a priority to kmalloc,
487		and you can specify the GFP_DMA flag if you need DMA-able memory.
488	
489		* Makefile: For source files that are loadable, always add name
490		to SCSI_SRCS.  Fill in modules: target.
491	
492		* hosts.c:  Change next_host to next_scsi_host, and make global.
493		Print hosts after we have identified all of them.  Use info()
494		function if present, otherwise use name field.
495	
496		* hosts.h: Change attach function to return int, not void.
497		Define number of device slots to allow for loadable devices.
498		Define tags to tell scsi module code what type of module we
499		are loading.
500	
501		* scsi.c: Fix scan_scsis so that it can be run by a user process.
502		Do not use waiting loops - use up and down mechanism as long
503		as current != task[0].
504	
505		* scsi.c(scan_scsis): Do not use stack variables for I/O - this
506		could be > 16Mb if we are loading a module at runtime (i.e. use
507		scsi_init_malloc to get some memory we know will be safe).
508	
509		* scsi.c: Change dma freelist to be a set of pages.  This allows
510		us to dynamically adjust the size of the list by adding more pages
511		to the pagelist.  Fix scsi_malloc and scsi_free accordingly.
512	
513		* scsi_module.c: Fix include.
514	
515		* sd.c: Declare detach function.  Increment/decrement module usage
516		count as required.  Fix init functions to allow loaded devices.
517		Revalidate all new disks so we get the partition tables.  Define
518		detach function.
519	
520		* sr.c: Likewise.
521	
522		* sg.c: Declare detach function.  Allow attachment of devices on
523		loaded drivers.
524	
525		* st.c: Declare detach function.  Increment/decrement module usage
526		count as required.

533	
534		* sr.c: Attacked by spelling bee...
535	
536		Patches from Gerd Knorr:
537	
538		* sr.c: make printk messages for photoCD a little more informative.
539	
540		* sr_ioctl.c: Fix CDROMMULTISESSION_SYS ioctl.
541	
542	Mon Jan  9 10:01:37 1995  Eric Youngdale  (eric@andante)

546		* Makefile: Add empty modules: target.
547	
548		* Wheee.  Now change register_iomem to request_region.
549	
550		* in2000.c: Bugfix - apparently this is the fix that we have
551		all been waiting for.  It fixes a problem whereby the driver
552		is not stable under heavy load.  Race condition and all that.
553		Patch from Peter Lu.
554

560	
561		Throughout:
562	
563			Change "snarf_region" with "register_iomem".
564	
565		* scsi_module.c: New file.  Contains support for low-level loadable
566		  scsi drivers. [ERY].
567	
568		* sd.c: More s/int/long/ changes.
569	
570		* seagate.c: Explicitly include linux/config.h
571	
572		* sg.c: Increment/decrement module usage count on open/close.
573	
574		* sg.c: Be a bit more careful about the user not supplying enough
575		  information for a valid command.  Pass correct size down to
576		  scsi_do_cmd.
577	
578		* sr.c:  More changes for Photo-CD.  This apparently breaks NEC drives.
579	
580		* sr_ioctl.c:  Support CDROMMULTISESSION ioctl.
581	
582

588	
589		* scsi.c (scsi_free): Change datatype of "offset" to long.
590		  (scsi_malloc): Change a few more variables to long.  Who
591		  did this and why was it important?  64 bit machines?
592	
593	
594		Lots of changes to use save_state/restore_state instead of cli/sti.
595		Files changed include:
596

678	
679		* sg.c: Bugfix - always use sg_free, since we might have big buff.
680	
681	Fri Dec  2 11:24:53 1994  Eric Youngdale  (eric@andante)
682	
683		* Linux 1.1.71 released.

702		* hosts.h: Add new forbidden_addr, forbidden_size fields.  Who
703		added these and why????
704	
705		* hosts.c (scsi_mem_init): Mark pages as reserved if they fall in
706		the forbidden regions.  I am not sure - I think this is so that
707		we can deal with boards that do incomplete decoding of their
708		address lines for the bios chips, but I am not entirely sure.
709	
710		* buslogic.c: Set forbidden_addr stuff if using a buggy board.
711	
712		* aha1740.c: Test for NULL pointer in SCtmp.  This should not

732		Only when SINGLE_HOST_OPERATIONS is defined.
733		Use new cmd_per_lun field.  [Dario]
734	
735		* eata.c: Likewise.

755	
756		* hosts.c: Initialize cmd_per_lun in Scsi_Hosts from template.
757	
758		* buslogic.c: Use cmd_per_lun field - initialize to different
759		values depending upon bus type (i.e. use 1 if ISA, so we do not
760		hog memory).  Use other patches which got lost from 1.1.68.
761	
762		* aha1542.c: Spelling.
763	
764	Tue Nov 29 15:43:50 1994  Eric Youngdale  (eric@andante.aib.com)

768		Add support for 12 byte vendor specific commands in scsi-generics,
769		more (i.e. the last mandatory) low-level changes to support
770		loadable modules, plus a few other changes people have requested
771		lately.  Changes by me (ERY) unless otherwise noted.  Spelling
772		changes appear from some unknown corner of the universe.
773	
774		* Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
775	
776		* Throughout: Change info() low level function to take a Scsi_Host
777		pointer.  This way the info function can return specific
778		information about the host in question, if desired.
779	
780		* All low-level drivers: Add NULL in initializer for the
781		usage_count field added to Scsi_Host_Template.

812		ISA motherboards.
813	
814		* hosts.h: Add usage_count to Scsi_Host_Template.

825		change setting when doing a request_sense, restore when done.
826		Move abort timeout message.  Fix panic in request_queueable to
827		print correct function name.
828	
829		* scsi.c: When incrementing usage count, walk block linked list
830		for host, and or in SCSI_HOST_BLOCK bit.  When decrementing usage
831		count to 0, clear this bit to allow usage to continue, wake up
832		processes waiting.
833	
834	
835		* scsi_ioctl.c: If we have an info() function, call it, otherwise
836		if we have a "name" field, use it, else do nothing.
837	
838		* sd.c, sr.c: Clear cmd_len field prior to each command we
839		generate.
840	
841		* sd.h: Add "has_part_table" bit to rscsi_disks.
842

845	
846		* sr.c: Bugfix from Gerd in photocd code.
847	
848		* sr.c: Bugfix in get_sectorsize - always use scsi_malloc buffer -
849		we cannot guarantee that the stack is < 16Mb.

1127	
1128		* scsicam.c: New file from Drew.  Read block 0 on the disk and
1129		read the partition table.  Attempt to deduce the geometry from
1130		the partition table if possible.  Only used by 53c[7,8]xx right
1131		now, but could be used by any device for which we have no way
1132		of identifying the geometry.
1133	
1134		* sd.c: Use device letters instead of sd%d in a lot of messages.
1135	
1136		* seagate.c: Fix bug that resulted in lockups with some devices.
1137	
1138		* sr.c (sr_open): Return -EROFS, not -EACCES if we attempt to open

1153	
1154		* t128.c: Update with minor cleanups.
1155

1157		id. Add Quantum LPS5235S to blacklist.  Change in_scan to
1158		in_scan_scsis and make global.
1159	
1160		* scsi.h: Add some defines for extended message handling,

1165	
1166

1168	
1169		* Linux 1.1.37 released.
1170	
1171		* aha1542.c: Always call aha1542_mbenable, use new udelay
1172		mechanism so we do not wait a long time if the board does not
1173		implement this command.
1174	
1175		* g_NCR5380.c: Remove #include <linux/config.h> and #if
1176		defined(CONFIG_SCSI_*).
1177	
1178		* seagate.c: Likewise.
1179	
1180		Next round of changes to support loadable modules.  Getting closer
1181		now, still not possible to do anything remotely usable.
1182	
1183		hosts.c: Create a linked list of detected high level devices.
1184		(scsi_register_device): New function to insert into this list.
1185		(scsi_init): Call scsi_register_device for each of the known high
1186		level drivers.
1187	
1188		hosts.h: Add prototype for linked list header.  Add structure
1189		definition for device template structure which defines the linked
1190		list.
1191	
1192		scsi.c: (scan_scsis): Use linked list instead of knowledge about
1193		existing high level device drivers.
1194		(scsi_dev_init): Use init functions for drivers on linked list
1195		instead of explicit list to initialize and attach devices to high
1196		level drivers.
1197	
1198		scsi.h: Add new field "attached" to scsi_device - count of number
1199		of high level devices attached.
1200	
1201		sd.c, sr.c, sg.c, st.c: Adjust init/attach functions to use new
1202		scheme.
1203

1205	
1206		* Linux 1.1.35 released.

1210	
1211	Thu Jul 21 10:37:39 1994  Eric Youngdale  (eric@esp22)
1212	
1213		* Linux 1.1.33 released.
1214	
1215		* sr.c(sr_open): Do not allow opens with write access.
1216	
1217	Mon Jul 18 09:51:22 1994  Eric Youngdale  (eric@esp22)
1218	
1219		* Linux 1.1.31 released.
1220	
1221		* sd.c: Increase SD_TIMEOUT from 300 to 600.

1224		used.
1225

1227	
1228	Sun Jul 17 16:25:29 1994  Eric Youngdale  (eric@esp22)
1229	
1230		* Linux 1.1.30 released.
1231	
1232		* scsi.c (scan_scsis): Fix detection of some Toshiba CDROM drives
1233		that report themselves as disk drives.
1234	
1235		* (Throughout): Use request.sem instead of request.waiting.
1236		Should fix swap problem with fdomain.
1237	
1238	Thu Jul 14 10:51:42 1994  Eric Youngdale  (eric@esp22)
1239	
1240		* Linux 1.1.29 released.
1241	
1242		* scsi.c (scan_scsis): Add new devices to end of linked list, not
1243		to the beginning.
1244	
1245		* scsi.h (SCSI_SLEEP): Remove brain dead hack to try to save
1246		the task state before sleeping.
1247	
1248	Sat Jul  9 15:01:03 1994  Eric Youngdale  (eric@esp22)
1249	
1250		More changes to eventually support loadable modules.  Mainly
1251		we want to use linked lists instead of arrays because it is easier
1252		to dynamically add and remove things this way.
1253	
1254		Quite a bit more work is needed before loadable modules are
1255		possible (and usable) with scsi, but this is most of the grunge
1256		work.
1257	
1258		* Linux 1.1.28 released.
1259	
1260		* scsi.c, scsi.h (allocate_device, request_queueable): Change
1261		argument from index into scsi_devices to a pointer to the
1262		Scsi_Device struct.
1263	
1264		* Throughout: Change all calls to allocate_device,
1265		request_queueable to use new calling sequence.
1266	
1267		* Throughout: Use SCpnt->device instead of
1268		scsi_devices[SCpnt->index].  Ugh - the pointer was there all along
1269		- much cleaner this way.
1270	
1271		* scsi.c (scsi_init_malloc, scsi_free_malloc): New functions -
1272		allow us to pretend that we have a working malloc when we
1273		initialize.  Use this instead of passing memory_start, memory_end
1274		around all over the place.
1275	
1276		* scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use
1277		scsi_init_malloc, remove all arguments, no return value.
1278	
1279		* scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
1280		structs.
1281	
1282		* scsi.c (scsi_dev_init): Set up for scsi_init_malloc.
1283		(scan_scsis): Get SDpnt from scsi_init_malloc, and refresh
1284		when we discover a device.  Free pointer before returning.
1285		Change scsi_devices into a linked list.
1286	
1287		* scsi.c (scan_scsis): Change to only scan one host.
1288		(scsi_dev_init): Loop over all detected hosts, and scan them.
1289	
1290		* hosts.c  (scsi_init_free): Change so that  number of extra bytes
1291		is stored in struct, and we do not have to pass it each time.
1292	
1293		* hosts.h: Change Scsi_Host_Template struct to include "next" and
1294		"release" functions.  Initialize to NULL in all low level
1295		adapters.
1296	
1297		* hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
1298		list scsi_hosts, linked together with the new "next" field.
1299	
1300	Wed Jul  6 05:45:02 1994  Eric Youngdale  (eric@esp22)
1301	
1302		* Linux 1.1.25 released.
1303	
1304		* aha152x.c: Changes from Juergen - cleanups and updates.
1305	
1306		* sd.c, sr.c: Use new check_media_change and revalidate
1307		file_operations fields.
1308	
1309		* st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
1310	
1311		* hosts.h: Change SG_ALL back to 0xff.  Apparently soft error
1312		in /dev/brain resulted in having this bumped up.
1313		Change first parameter in bios_param function to be Disk * instead
1314		of index into rscsi_disks.
1315	
1316		* sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
1317		to array.
1318	
1319		* sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
1320	
1321		* scsi.c: Remove redundant Maxtor XT8760S from blacklist.
1322		In scsi_reset, add printk when DEBUG defined.
1323	
1324		* All low level drivers: Modify definitions of bios_param in
1325		appropriate way.
1326	
1327	Thu Jun 16 10:31:59 1994  Eric Youngdale  (eric@esp22)
1328	
1329		* Linux 1.1.20 released.
1330	
1331		* scsi_ioctl.c: Only pass down the actual number of characters
1332		required to scsi_do_cmd, not the one rounded up to a even number
1333		of sectors.
1334	
1335		* ultrastor.c: Changes from Caleb Epstein for 24f cards.  Support
1336		larger SG lists.
1337	
1338		* ultrastor.c: Changes from me - use scsi_register to register
1339		host.  Add some consistency checking,
1340	
1341	Wed Jun  1 21:12:13 1994  Eric Youngdale  (eric@esp22)
1342	
1343		* Linux 1.1.19 released.
1344	
1345		* scsi.h: Add new return code for reset() function:
1346		SCSI_RESET_PUNT.
1347	
1348		* scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for
1349		now.
1350	
1351		* aha1542.c: If the command responsible for the reset is not
1352		pending, return SCSI_RESET_PUNT.
1353	
1354		* aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
1355		SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
1356	
1357	Tue May 31 19:36:01 1994  Eric Youngdale  (eric@esp22)
1358	
1359		* buslogic.c: Do not print out message about "must be Adaptec"
1360		if we have detected a buslogic card.  Print out a warning message
1361		if we are configuring for >16Mb, since the 445S at board level
1362		D or earlier does not work right.  The "D" level board can be made
1363		to work by flipping an undocumented switch, but this is too subtle.
1364	
1365	    Changes based upon patches in Yggdrasil distribution.
1366	
1367		* sg.c, sg.h: Return sense data to user.
1368	
1369		* aha1542.c, aha1740.c, buslogic.c: Do not panic if
1370		sense buffer is wrong size.
1371	
1372		* hosts.c: Test for ultrastor card before any of the others.
1373	
1374		* scsi.c: Allow boot-time option for max_scsi_luns=? so that
1375		buggy firmware has an easy work-around.
1376	
1377	Sun May 15 20:24:34 1994  Eric Youngdale  (eric@esp22)
1378	
1379		* Linux 1.1.15 released.
1380	
1381		Post-codefreeze thaw...
1382	
1383		* buslogic.[c,h]: New driver from David Gentzel.
1384	
1385		* hosts.h: Add use_clustering field to explicitly say whether
1386		clustering should be used for devices attached to this host
1387		adapter.  The buslogic board apparently supports large SG lists,
1388		but it is apparently faster if sd.c condenses this into a smaller
1389		list.
1390	
1391		* sd.c: Use this field instead of heuristic.
1392	
1393		* All host adapter include files: Add appropriate initializer for
1394		use_clustering field.
1395	
1396		* scsi.h: Add #defines for return codes for the abort and reset
1397		functions.  There are now a specific set of return codes to fully
1398		specify all of the possible things that the low-level adapter
1399		could do.
1400	
1401		* scsi.c: Act based upon return codes from abort/reset functions.
1402	
1403		* All host adapter abort/reset functions: Return new return code.
1404	
1405		* Add code in scsi.c to help debug timeouts.  Use #define
1406		DEBUG_TIMEOUT to enable this.
1407	
1408		* scsi.c: If the host->irq field is set, use
1409		disable_irq/enable_irq before calling queuecommand if we
1410		are not already in an interrupt.  Reduce races, and we
1411		can be sloppier about cli/sti in the interrupt routines now
1412		(reduce interrupt latency).
1413	
1414		* constants.c: Fix some things to eliminate warnings.  Add some
1415		sense descriptions that were omitted before.
1416	
1417		* aha1542.c: Watch for SCRD from host adapter - if we see it, set
1418		a flag.  Currently we only print out the number of pending
1419		commands that might need to be restarted.
1420	
1421		* aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
1422		full, and attempt to recover.  Otherwise give up.
1423	
1424		* aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass
1425		DID_RESET back up to the upper level code for all commands running
1426		on this target (even on different LUNs).
1427	
1428	Sat May  7 14:54:01 1994
1429	
1430		* Linux 1.1.12 released.
1431	
1432		* st.c, st.h: New version from Kai.  Supports boot time
1433		specification of number of buffers.
1434	
1435		* wd7000.[c,h]: Updated driver from John Boyd.  Now supports
1436		more than one wd7000 board in machine at one time, among other things.
1437	
1438	Wed Apr 20 22:20:35 1994
1439	
1440		* Linux 1.1.8 released.
1441	
1442		* sd.c: Add a few type casts where scsi_malloc is called.
1443	
1444	Wed Apr 13 12:53:29 1994
1445	
1446		* Linux 1.1.4 released.
1447	
1448		* scsi.c: Clean up a few printks (use %p to print pointers).
1449	
1450	Wed Apr 13 11:33:02 1994
1451	
1452		* Linux 1.1.3 released.
1453	
1454		* fdomain.c: Update to version 5.16 (Handle different FIFO sizes
1455		better).
1456	
1457	Fri Apr  8 08:57:19 1994
1458	
1459		* Linux 1.1.2 released.
1460

1650		know to restart the command.  Change prototype of aha1740_reset
1651		to take a command pointer.
1652	
1653		* constants.c: Clean up a few things.
1654	
1655		* fdomain.c: Update to version 5.6.  Move snarf_region.  Allow

1667		and add Maxtor MXT-1240S, XT-4170S, NEC CDROM 84, Seagate ST157N.
1668	
1669		* scsi.h: Add constants for tagged queueing.
1670	
1671		* Throughout: Use constants from major.h instead of hardcoded
1672		numbers for major numbers.
1673	
1674		* scsi_ioctl.c: Fix bug in buffer length in ioctl_command.  Use
1675		verify_area in GET_IDLUN ioctl.  Add new ioctls for
1676		TAGGED_QUEUE_ENABLE, DISABLE.  Only allow IOCTL_SEND_COMMAND by
1677		superuser.
1678	
1679		* sd.c: Only pay attention to UNIT_ATTENTION for removable disks.
1680		Fix bug where sometimes portions of blocks would get lost
1681		resulting in processes hanging.  Add messages when we spin up a
1682		disk, and fix a bug in the timing.  Increase read-ahead for disks
1683		that are on a scatter-gather capable host adapter.
1684	
1685		* seagate.c: Fix so that some parameters can be set from the lilo
1686		prompt.  Supply jumpstart flag if we are resetting and need the
1687		command restarted.   Fix so that we return 1 if we detect a card
1688		so that multiple card detection works correctly.  Add yet another
1689		signature for FD cards (950).  Add another signature for ST0x.
1690	
1691		* sg.c, sg.h: New files from Lawrence Foard for generic scsi
1692		access.
1693	
1694		* sr.c:  Add type casts for (void*) so that we can do pointer
1695		arithmetic.  Works with GCC without this, but it is not strictly
1696		correct.  Same bugfix as was in sd.c.  Increase read-ahead a la
1697		disk driver.
1698	
1699		* sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
1700		since we cannot guarantee that the stack is < 16Mb.
1701	
1702		ultrastor.c: Update to support 24f properly (JFC's driver).
1703	
1704		wd7000.c: Supply jumpstart flag for reset.  Do not round up

1714	    * aha1542.c: Do hard reset instead of soft (some ethercard probes
1715	    screw us up).
1716	
1717	    * scsi.c: Add new flag ASKED_FOR_SENSE so that we can tell if we are
1718	    in a loop whereby the device returns null sense data.
1719	
1720	    * sd.c: Add code to spin up a drive if it is not already spinning.
1721	    Do this one at a time to make it easier on power supplies.

1736	    * Makefile: Do not try to count the number of low-level drivers,
1737	    just generate the list of .o files.
1738	
1739	    * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer).  Add tests
1740	    for addresses > 16Mb, panic if we find one.
1741	
1742	    * aha1740.c: Ditto with sizeof().
1743	
1744	    * fdomain.c: Update to version 3.18.  Add new signature, register IRQ
1745	    with irqaction.  Use ID 7 for new board.  Be more intelligent about
1746	    obtaining the h/s/c numbers for biosparam.
1747	
1748	    * hosts.c: Do not depend upon Makefile generated count of the number
1749	    of low-level host adapters.
1750	
1751	    * scsi.c: Use array for scsi_command_size instead of a function.  Add
1752	    Texel cdrom and Maxtor XT-4380S to blacklist.  Allow compile time
1753	    option for no-multi lun scan.  Add semaphore for possible problems
1754	    with handshaking, assume device is faulty until we know it not to be
1755	    the case.  Add DEBUG_INIT symbol to dump info as we scan for devices.
1756	    Zero sense buffer so we can tell if we need to request it.  When
1757	    examining sense information, request sense if buffer is all zero.
1758	    If RESET, request sense information to see what to do next.
1759	
1760	    * scsi_debug.c: Change some constants to use symbols like INT_MAX.
1761	
1762	    * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
1763	    calls from kernel space.
1764	
1765	    * sd.c: Increase timeout to 300.  Use functions in constants.h to
1766	    display info.  Use scsi_malloc buffer for READ_CAPACITY, since
1767	    we cannot guarantee that a stack based buffer is < 16Mb.
1768	
1769	    * sd_ioctl.c: Add BLKFLSBUF ioctl.
1770	
1771	    * seagate.c: Add new compile time options for ARBITRATE,
1772	    SLOW_HANDSHAKE, and SLOW_RATE.  Update assembly loops for transferring

1780	    unchecked_isa_dma flag, even though this may not be needed (gets set
1781	    later).
1782	
1783	Sat Jul 17 18:32:44 1993
1784	
1785	    * 0.99pl11 released.  C++ compilable.

1796	
1797	    * fdomain.c: Update to version 3.17 from 3.6.  Now works with
1798	    TMC-18C50.
1799	
1800	    * scsi.c: Minor changes here and there with datatypes.  Save use_sg
1801	    when requesting sense information so that this can properly be
1802	    restored if we retry the command.  Set aside dma buffers assuming each
1803	    block is 1 page, not 1Kb minix block.
1804	
1805	    * scsi_ioctl.c: Add a few type casts.  Other minor changes.
1806	
1807	    * sd.c:  Correctly  free all scsi_malloc'd memory if we run out of

1810	    * seagate.c: Minor cleanups here and there.
1811	
1812	    * sr.c: Set up blocksize array for all discs.  Fix bug in freeing

1827	    * sd.c: Add block_fsync function to dispatch table.
1828	
1829	    * sr.c: Increase timeout to 500 from 250.  Add entry for sync in
1830	    dispatch table (supply NULL).  If we do not have a sectorsize,
1831	    try to get it in the sd_open function.  Add new function just to
1832	    obtain sectorsize.
1833	
1834	    * sr.h: Add needs_sector_size semaphore.
1835	
1836	    * st.c: Add NULL for fsync in dispatch table.
1837	
1838	    * wd7000.c: Allow another condition for power on that are normal

1889	    * scsi.h: Define COMMAND_SIZE.  Define a SCSI specific version of
1890	    INIT_REQUEST that can run with interrupts off.
1891	
1892	    * scsi_ioctl.c: Make ioctl_probe function more idiot-proof.  If
1893	    a removable device says ILLEGAL REQUEST to a door-locking command,
1894	    clear lockable flag.  Add SCSI_IOCTL_GET_IDLUN ioctl.  Do not attempt
1895	    to lock door for devices that do not have lockable semaphore set.
1896	
1897	    * sd.c: Fix race condition for multiple disks.  Use INIT_SCSI_REQUEST
1898	    instead of INIT_REQUEST.  Allow sector sizes of 1024 and 256.  For
1899	    removable disks that are not ready, mark them as having a media change
1900	    (some drives do not report this later).
1901	
1902	    * seagate.c: Use volatile keyword for memory-mapped register pointers.
1903	
1904	    * sr.c: Fix race condition, a la sd.c.  Increase the number of retries
1905	    to 1.  Use INIT_SCSI_REQUEST.  Allow 512 byte sector sizes.  Do a
1906	    read_capacity when we init the device so we know the size and
1907	    sectorsize.

1909	    * st.c: If ioctl not found in st.c, try scsi_ioctl for others.
1910	
1911	    * ultrastor.c: Do not truncate number of cylinders at 1024 for
1912	    biosparam call.
1913	
1914	    * wd7000.c: Ditto.
1915	    Throughout: Use COMMAND_SIZE macro to determine length of scsi

1925	    verify_area syntax.
1926	
1927	    * aha1542.c: Handle unexpected interrupts better.
1928	
1929	    * scsi.c: Ditto.  Handle reset conditions a bit better, asking for
1930	    sense information and retrying if required.
1931	
1932	    * scsi_ioctl.c: Allow for 12 byte scsi commands.
1933	
1934	    * ultrastor.c: Update to use scatter-gather.

1967	    with SCint to fix race condition.  Use recursion_depth to keep track
1968	    of how many times we have been recursively called, and do not start
1969	    another command unless we are on the outer level.  Fixes bug
1970	    with Syquest cartridge drives (used to crash kernel), because
1971	    they do not disconnect with large data transfers.

1981	    non-buffer type of request.
1982	
1983	    * seagate.c:  Allow controller to be overridden with CONTROLLER symbol.
1984	    Set SCint=NULL when we are done, to remove race condition.
1985	
1986	    * st.c: Changes from Kai.
1987	
1988	Wed Dec 30 20:03:47 1992
1989	
1990	    * 0.99pl2 released.
1991

1993	    eliminates need for it here.
1994	
1995	    * sd.c: Return ENODEV instead of EACCES if no such device available.
1996	    (sd_init) Init blkdev_fops earlier so that sd_open is available sooner.
1997	
1998	    * sr.c: Same as above for sd.c.
1999	
2000	    * st.c: Return ENODEV instead of ENXIO if no device.  Init chrdev_fops
2001	    sooner, so that it is always there even if no tapes.
2002	
2003	    * seagate.c (controller_type): New variable to keep track of ST0x or
2004	    FD.  Modify signatures list to indicate controller type, and init
2005	    controller_type once we find a match.

2014	    NR_SCSI_DEVICES.
2015	
2016	    * sr_ioctl.c: Verify that device exists before allowing an ioctl.
2017	
2018	    * st.c: Patches from Kai - change timeout values, improve end of tape
2019	    handling.
2020
