-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.

Trying to find an issue in the dentry cache? Try
- slub_debug=,dentry_cache
+ slub_debug=,dentry
to only enable debugging on the dentry cache.
Red zoning and tracking may realign the slab. We can just apply sanity checks
to the dentry cache with
- slub_debug=F,dentry_cache
+ slub_debug=F,dentry
In case you forgot to enable debugging on the kernel command line: It is
possible to enable debugging manually when the kernel is up. Look at the

/*
- * This module provides support for the bus-master IDE DMA functions
- * of various PCI chipsets, including the Intel PIIX (i82371FB for
- * the 430 FX chipset), the PIIX3 (i82371SB for the 430 HX/VX and
- * 440 chipsets), and the PIIX4 (i82371AB for the 430 TX chipset)
- * ("PIIX" stands for "PCI ISA IDE Xcellerator").
- *
- * Pretty much the same code works for other IDE PCI bus-mastering chipsets.
- *
- * DMA is supported for all IDE devices (disk drives, cdroms, tapes, floppies).
- *
- * By default, DMA support is prepared for use, but is currently enabled only
- * for drives which already have DMA enabled (UltraDMA or mode 2 multi/single),
- * or which are recognized as "good" (see table below). Drives with only mode0
- * or mode1 (multi/single) DMA should also work with this chipset/driver
- * (eg. MC2112A) but are not enabled by default.
- *
- * Use "hdparm -i" to view modes supported by a given drive.
- *
- * The hdparm-3.5 (or later) utility can be used for manually enabling/disabling
- * DMA support, but must be (re-)compiled against this kernel version or later.
- *
- * To enable DMA, use "hdparm -d1 /dev/hd?" on a per-drive basis after booting.
- * If problems arise, ide.c will disable DMA operation after a few retries.
- * This error recovery mechanism works and has been extremely well exercised.
- *
- * IDE drives, depending on their vintage, may support several different modes
- * of DMA operation. The boot-time modes are indicated with a "*" in
- * the "hdparm -i" listing, and can be changed with *knowledgeable* use of
- * the "hdparm -X" feature. There is seldom a need to do this, as drives
- * normally power-up with their "best" PIO/DMA modes enabled.
- *
- * Testing has been done with a rather extensive number of drives,
- * with Quantum & Western Digital models generally outperforming the pack,
- * and Fujitsu & Conner (and some Seagate which are really Conner) drives
- * showing more lackluster throughput.
- *
- * Keep an eye on /var/adm/messages for "DMA disabled" messages.
- *
- * Some people have reported trouble with Intel Zappa motherboards.
- * This can be fixed by upgrading the AMI BIOS to version 1.00.04.BS0,
- * available from ftp://ftp.intel.com/pub/bios/10004bs0.exe
- * (thanks to Glen Morrell <glen@spin.Stanford.edu> for researching this).
- *
* Thanks to "Christopher J. Reimer" <reimer@doe.carleton.ca> for
* fixing the problem with the BIOS on some Acer motherboards.
*
*
* Most importantly, thanks to Robert Bringman <rob@mars.trion.com>
* for supplying a Promise UDMA board & WD UDMA drive for this work!
- *
- * And, yes, Intel Zappa boards really *do* use both PIIX IDE ports.
- *
- * ATA-66/100 and recovery functions, I forgot the rest......

- *
- * $Log: uaccess.h,v $
- * Revision 1.8 2001/10/29 13:01:48 bjornw
- * Removed unused variable tmp2 in strnlen_user
- *
- * Revision 1.7 2001/10/02 12:44:52 hp
- * Add support for 64-bit put_user/get_user
- *
- * Revision 1.6 2001/10/01 14:51:17 bjornw
- * Added register prefixes and removed underscores
- *
- * Revision 1.5 2000/10/25 03:33:21 hp
- * - Provide implementation for everything else but get_user and put_user;
- * copying inline to/from user for constant length 0..16, 20, 24, and
- * clearing for 0..4, 8, 12, 16, 20, 24, strncpy_from_user and strnlen_user
- * always inline.
- * - Constraints for destination addr in get_user cannot be memory, only reg.
- * - Correct labels for PC at expected fault points.
- * - Nits with assembly code.
- * - Don't use statement expressions without value; use "do {} while (0)".
- * - Return correct values from __generic_... functions.
- *
- * Revision 1.4 2000/09/12 16:28:25 bjornw
- * * Removed comments from the get/put user asm code
