Paul Walmsley 28120be5d6 [PATCH] USB Storage: Force starget->scsi_level in usb-storage scsiglue.c
When the usb-storage module forces sdev->scsi_level to SCSI_2, it should
also force starget->scsi_level to the same value.  Otherwise, the SCSI
layer may attempt to issue SCSI-3 commands to the device, such as REPORT
LUNS, which it cannot handle.  This can prevent the device from working
with Linux.

The AMS Venus DS3 DS2316SU2S SATA-to-SATA+USB enclosure, based on the
Oxford Semiconductor OXU921S chip, requires this patch to function
correctly on Linux.  The enclosure reports a SCSI-3 SPC-2 command set
level, but does not correctly handle the REPORT LUNS SCSI command -
probably due to a bug in its firmware.

It seems likely that other USB storage enclosures with similar bugs will
also benefit from this patch.

Tony Lindgren <tony@atomide.com> collaborated in the development of this
patch.

Matthew Dharm 226173edae [PATCH] USB: storage: Fix messed-up locking
This is patch as550 from Alan Stern.

Apparently someone changed the SCSI core so that it no longer holds the
host lock when doing a device or bus reset.  usb-storage was updated at
the time, but the change was done carelessly.  Some of the code depends
on that lock being held.

This patch reintroduces the host lock where needed and tries to clarify
the comments explaining why the lock is necessary.  It also moves the
code that clears the TIMED_OUT and ABORTING bitflags so that it executes
as soon as the timed-out command has completed (and while the host lock
is held).

Matthew Dharm a4e628328e [PATCH] USB Storage: wedge SCSI revision at 2 for usb-storage devices
This patch started life as as479b, and has been rediffed.  Please note
the order of submission of this latest patch series -- even tho this has
an older original number, it is the last patch I'll be sending today.

This patch changes the reported SCSI revision level to 2 for all
disk-type devices.  This is needed in a few cases because the device
reports a level of 3 or higher but then crashes when given a REPORT LUNS
command (for which support is supposed to be mandatory at those levels).
This shouldn't harm us, since it only matters for sparse LUNs and we
have separate ways of coping with that.

Matthew Dharm 86dbde9cbd [PATCH] USB Storage: retry hard errors
This patch started life as as527, and was rediffed by me.

Since the IDE interface doesn't convey much information about types of
errors, many USB-IDE adapters report all low-level errors with SK = 0x04,
which is supposed to be used only for non-recoverable errors.  As a result
the SCSI midlayer doesn't retry the command.  But quite often a retry
would succeed, whereas an unnecessary retry doesn't really hurt anything.

This patch uses a recently-implemented flag to tell the SCSI midlayer that
such hardware errors should be retried.

Matthew Dharm 4d07ef762f [PATCH] USB Storage: port reset on transport error
This patch causes a port reset whenever there's a transport error or abort.
If that fails it reverts back to doing a mass-storage device reset.  It
started life as as497 and was rediffed by me.

This makes error recovery a lot quicker and more reliable.

Linus Torvalds 1da177e4c3 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!
