What: ide-tape driver
When: July 2008
Files: drivers/ide/ide-tape.c
Why: This driver might not have any users anymore and maintaining it for no
reason is an effort no one wants to make.

What: libata spindown skipping and warning
When: Dec 2008
Why: Some halt(8) implementations synchronize caches for and spin
@ -306,3 +316,15 @@ Why: Largely unmaintained and almost entirely unused. File system
is largely pointless as without a lot of work only the most
trivial of Solaris binaries can work with the emulation code.
Who: David S. Miller <davem@davemloft.net>
---------------------------
What: init_mm export
When: 2.6.26
Why: Not used in-tree. The current out-of-tree users used it to
work around problems in the CPA code which should be resolved
by now. One usecase was described to provide verification code
of the CPA operation. That's a good idea in general, but such
code / infrastructure should be in the kernel and not in some
out-of-tree driver.

As for VLB, it is safest to not specify it.
Bigger values are safer than smaller ones.
"idex=noprobe" : do not attempt to access/use this interface
"idex=base" : probe for an interface at the addr specified,
where "base" is usually 0x1f0 or 0x170
and "ctl" is assumed to be "base"+0x206

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 /dev/MAKEDEV 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.
