Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ *
+ * $Id: isd200.c,v 1.16 2002/04/22 03:39:43 mdharm Exp $
+ *
+ * Current development and maintenance:
+ * (C) 2001-2002 Björn Stenberg (bjorn@haxx.se)
+ *
+ * Developed with the assistance of:
+ * (C) 2002 Alan Stern <stern@rowland.org>
+ *
+ * Initial work:
+ * (C) 2000 In-System Design, Inc. (support@in-system.com)
+ *
+ * The ISD200 ASIC does not natively support ATA devices. The chip
+ * does implement an interface, the ATA Command Block (ATACB) which provides
+ * a means of passing ATA commands and ATA register accesses to a device.

+ * History:
+ *
+ * 2002-10-19: Removed the specialized transfer routines.
+ * (Alan Stern <stern@rowland.harvard.edu>)
+ * 2001-02-24: Removed lots of duplicate code and simplified the structure.
+ * (bjorn@haxx.se)
+ * 2002-01-16: Fixed endianness bug so it works on the ppc arch.
+ * (Luc Saillard <luc@saillard.org>)
+ * 2002-01-17: All bitfields removed.

+ * SCSI Connecting Glue Header File
+ *
+ * $Id: scsiglue.h,v 1.4 2000/08/25 00:13:51 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices. Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document. The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
+ *
+ * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
+ * information about this driver.

+ *
+ * $Id: shuttle_usbat.c,v 1.17 2002/04/22 03:39:43 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 2000, 2001 Robert Baruch (autophile@starband.net)
+ * (c) 2004, 2005 Daniel Drake <dsd@gentoo.org>
+ *
+ * Developed with the assistance of:
+ * (c) 2002 Alan Stern <stern@rowland.org>
+ *
+ * Flash support based on earlier work by:
+ * (c) 2002 Thomas Kreiling <usbdev@sm04.de>
+ *
+ * Many originally ATAPI devices were slightly modified to meet the USB
+ * market by using some kind of translation from ATAPI to USB on the host,
+ * and the peripheral would translate from USB back to ATAPI.
+ *
+ * SCM Microsystems (www.scmmicro.com) makes a device, sold to OEM's only,
+ * which does the USB-to-ATAPI conversion. By obtaining the data sheet on
+ * their device under nondisclosure agreement, I have been able to write
+ * this driver for Linux.
+ *
+ * The chip used in the device can also be used for EPP and ISA translation
+ * as well. This driver is only guaranteed to work with the ATAPI
+ * translation.
+ *
+ * See the Kconfig help text for a list of devices known to be supported by
+ * this driver.

+/* Driver for USB Mass Storage compliant devices
+ *
+ * $Id: transport.c,v 1.47 2002/04/22 03:39:43 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * Developed with the assistance of:
+ * (c) 2000 David L. Brown, Jr. (usb-storage@davidb.org)
+ * (c) 2000 Stephen J. Gowdy (SGowdy@lbl.gov)
+ * (c) 2002 Alan Stern <stern@rowland.org>
+ *
+ * Initial work by:
+ * (c) 1999 Michael Gee (michael@linuxspecific.com)
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices. Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document. The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
+ *
+ * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
+ * information about this driver.

+/*
+ * This is subtle, so pay attention:
+ * ---------------------------------
+ * We're very concerned about races with a command abort. Hanging this code
+ * is a sure fire way to hang the kernel. (Note that this discussion applies
+ * only to transactions resulting from a scsi queued-command, since only
+ * these transactions are subject to a scsi abort. Other transactions, such
+ * as those occurring during device-specific initialization, must be handled
+ * by a separate code path.)
+ *
+ * The abort function (usb_storage_command_abort() in scsiglue.c) first
+ * sets the machine state and the ABORTING bit in us->flags to prevent
+ * new URBs from being submitted. It then calls usb_stor_stop_transport()
+ * below, which atomically tests-and-clears the URB_ACTIVE bit in us->flags
+ * to see if the current_urb needs to be stopped. Likewise, the SG_ACTIVE
+ * bit is tested to see if the current_sg scatter-gather request needs to be
+ * stopped. The timeout callback routine does much the same thing.
+ *
+ * When a disconnect occurs, the DISCONNECTING bit in us->flags is set to
+ * prevent new URBs from being submitted, and usb_stor_stop_transport() is
+ * called to stop any ongoing requests.
+ *
+ * The submit function first verifies that the submitting is allowed
+ * (neither ABORTING nor DISCONNECTING bits are set) and that the submit
+ * completes without errors, and only then sets the URB_ACTIVE bit. This
+ * prevents the stop_transport() function from trying to cancel the URB
+ * while the submit call is underway. Next, the submit function must test
+ * the flags to see if an abort or disconnect occurred during the submission
+ * or before the URB_ACTIVE bit was set. If so, it's essential to cancel
+ * the URB if it hasn't been cancelled already (i.e., if the URB_ACTIVE bit
+ * is still set). Either way, the function must then wait for the URB to
+ * finish. Note that because the URB_ASYNC_UNLINK flag is set, the URB can
+ * still be in progress even after a call to usb_unlink_urb() returns.
+ *
+ * The idea is that (1) once the ABORTING or DISCONNECTING bit is set,
+ * either the stop_transport() function or the submitting function
+ * is guaranteed to call usb_unlink_urb() for an active URB,
+ * and (2) test_and_clear_bit() prevents usb_unlink_urb() from being
+ * called more than once or from being called during usb_submit_urb().

+ * Transport Functions Header File
+ *
+ * $Id: transport.h,v 1.18 2002/04/21 02:57:59 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 1999, 2000 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices. Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document. The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
+ *
+ * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
+ * information about this driver.

+/* Driver for USB Mass Storage compliant devices
+ *
+ * $Id: usb.c,v 1.75 2002/04/22 03:39:43 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 1999-2003 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * Developed with the assistance of:
+ * (c) 2000 David L. Brown, Jr. (usb-storage@davidb.org)
+ * (c) 2003 Alan Stern (stern@rowland.harvard.edu)
+ *
+ * Initial work by:
+ * (c) 1999 Michael Gee (michael@linuxspecific.com)
+ *
+ * usb_device_id support by Adam J. Richter (adam@yggdrasil.com):
+ * (c) 2000 Yggdrasil Computing, Inc.
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices. Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document. The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
+ *
+ * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
+ * information about this driver.

+/* Driver for USB Mass Storage compliant devices
+ * Main Header File
+ *
+ * $Id: usb.h,v 1.21 2002/04/21 02:57:59 mdharm Exp $
+ *
+ * Current development and maintenance by:
+ * (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
+ *
+ * Initial work by:
+ * (c) 1999 Michael Gee (michael@linuxspecific.com)
+ *
+ * This driver is based on the 'USB Mass Storage Class' document. This
+ * describes in detail the protocol used to communicate with such
+ * devices. Clearly, the designers had SCSI and ATAPI commands in
+ * mind when they created this document. The commands are all very
+ * similar to commands in the SCSI-II and ATAPI specifications.
+ *
+ * It is important to note that in a number of cases this class
+ * exhibits class-specific exemptions from the USB specification.
+ * Notably the usage of NAK, STALL and ACK differs from the norm, in
+ * that they are used to communicate wait, failed and OK on commands.
+ *
+ * Also, for certain devices, the interrupt endpoint is used to convey
+ * status of a command.
+ *
+ * Please see http://www.one-eyed-alien.net/~mdharm/linux-usb for more
+ * information about this driver.
