We all failed to notice that Franck's recent update to usb-storage allowed
an URB to complete after its context data was no longer valid. This patch
(as746) makes the driver wait for the URB to complete whenever there's a
timeout.
Although timeouts in usb-storage are relatively uncommon, they do occur.
Without this patch the code in 2.6.18-rc1 will fault within an interrupt
handler, which is not nice at all.

Usually we don't care much about 'gcc -W' warnings, but some of us do build
kernels that way to look for problems, and then the fewer warnings we have
to wade through the better. Especially when they are very easy and
non-intrusive to clean up. Which is the case for the following warnings
spewed by drivers/usb/storage/usb.h :
drivers/usb/storage/usb.h:163: warning: `inline' is not at beginning of
+declaration
drivers/usb/storage/usb.h:166: warning: `inline' is not at beginning of
+declaration
There's also some precedence for cleaning up these warnings. I've had
a few patches merged in the past that remove exactly this class of
warnings.

After some further testing with my flash device I realised that our current
probe doesn't always work (e.g. when no media is inserted).
Now that Peter Chubb's patch has simplified the detection of 99% of the HP CD
writers out there, we have a much smaller range of hardware to work with on
the shared device ID, so it should be possible to try some of the previous
probe options again: we just need to find another tester with a USBAT2-based HP
CD writer.
This patch hardcodes the flash detection until someone comes along with one of
these obscure CD drives. Note that these devices are extremely rare, so even if
we can't ever find a decent probe method, at least we will be supporting almost
all of the USBAT-based hardware out there.

I've worked out what's going wrong. The scsi layer is now much
more likely to pass down scatterlists instead of plain buffers. So
you have to make sure that they're handled correctly. In one of the
changes along the way, usbat_write_block and friends stopped obeying
the srb->use_sg flag.
Anyway, with the appended patch, and the one I'm putting in the next email, it
all seems to work for the HP cd4e. Of course, someone's going to have
to test it with the flash drives as well....
This patch teaches the usbat_{read,write}_block functions to
obey the use_sg flag in the scsi-request.

This patch adds another usb-storage subdriver, which supports two fairly
old dual-XD/SmartMedia reader-writers (USB1.1 devices).
This driver was written by Daniel Drake <dsd@gentoo.org> -- he notes
that he wrote this driver without specs, however a vendor-supplied GPL
driver for the previous generation of products ("sma03") did prove to be
quite useful, as did the sddr09 driver which also has to deal with
low-level physical block layout on SmartMedia.
The original patch has been reformed by me, as it clashed with the
libusual patches.
We really need to consolidate some of this common SmartMedia code, and
get together with the MTD guys to share it with them as well.

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.
