IDE ATAPI streaming tape driver
-------------------------------
This driver is a part of the Linux ide driver and works in co-operation
with linux/drivers/block/ide.c.
The driver, in co-operation with ide.c, basically traverses the
request-list for the block device interface. The character device
interface, on the other hand, creates new requests, adds them
to the request-list of the block device, and waits for their completion.
Pipelined operation mode is now supported on both reads and writes.
The block device major and minor numbers are determined from the
tape's relative position in the ide interfaces, as explained in ide.c.
The character device interface consists of the following devices:
ht0 major 37, minor 0 first IDE tape, rewind on close.
ht1 major 37, minor 1 second IDE tape, rewind on close.
...
nht0 major 37, minor 128 first IDE tape, no rewind on close.
nht1 major 37, minor 129 second IDE tape, no rewind on close.
...
Run linux/scripts/MAKEDEV.ide to create the above entries.
The general magnetic tape commands compatible interface, as defined by
include/linux/mtio.h, is accessible through the character device.
General ide driver configuration options, such as the interrupt-unmask
flag, can be configured by issuing an ioctl to the block device interface,
as any other ide device.
Our own ide-tape ioctl's can be issued to either the block device or
the character device interface.
Maximal throughput with minimal bus load will usually be achieved in the
following scenario:
1. ide-tape is operating in the pipelined operation mode.
2. No buffering is performed by the user backup program.

*
* Emulation of a SCSI host adapter for IDE ATAPI devices.
*
* With this driver, one can use the Linux SCSI drivers instead of the
* native IDE ATAPI drivers.
*
* Ver 0.1 Dec 3 96 Initial version.
* Ver 0.2 Jan 26 97 Fixed bug in cleanup_module() and added emulation
* of MODE_SENSE_6/MODE_SELECT_6 for cdroms. Thanks
* to Janos Farkas for pointing this out.
* Avoid using bitfields in structures for m68k.
* Added Scatter/Gather and DMA support.
* Ver 0.4 Dec 7 97 Add support for ATAPI PD/CD drives.
* Use variable timeout for each command.
* Ver 0.5 Jan 2 98 Fix previous PD/CD support.
* Allow disabling of SCSI-6 to SCSI-10 transformation.
* Ver 0.6 Jan 27 98 Allow disabling of SCSI command translation layer
* for access through /dev/sg.
* Fix MODE_SENSE_6/MODE_SELECT_6/INQUIRY translation.
* Ver 0.7 Dec 04 98 Ignore commands where lun != 0 to avoid multiple
* detection of devices with CONFIG_SCSI_MULTI_LUN
* Ver 0.8 Feb 05 99 Optical media need translation too. Reverse 0.7.
* Ver 0.9 Jul 04 99 Fix a bug in SG_SET_TRANSFORM.
