This is necessary to make some storage arrays work.
Some storage devices have more than 8 LUNs. In addition
you can hook up a WideSCSI bus to USB. In these cases even
level 2 devices can have more than 8 LUNs. For them
it is necessary to simply believe the class specific
command and report its result back to the SCSI layer.

which is listed along with 04E6:000B in the Windows INF file for the
Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)".
The already-present quirk for 04E6:000B has USB_SC_SCSI/USB_PR_BULK, not

Our detection logic to avoid doing UAS on ASM1051 bridge chips causes problems
with newer ASM1153 disk enclosures in 2 ways:
1) Some ASM1153 disk enclosures re-use the ASM1051 device-id of 5106, which
we assume is always an ASM1051, so remove the quirk for 5106, and instead
use the same detection logic as we already use for device-id 55aa, which is
used for all of ASM1051, ASM1053 and ASM1153 devices <sigh>.
2) Our detection logic to differentiate between ASM1051 and ASM1053 sees
ASM1153 devices as ASM1051 because they have 32 streams like ASM1051 devs.
Luckily the ASM1153 descriptors are not 100% identical, unlike the previous
models the ASM1153 has bMaxPower == 0, so use that to differentiate it.

This patch does two things for SCM eUSCSI USB-SCSI converters:
1. SCM eUSCSI bridge devices are hard-wired to use SCSI ID 7. On connecting
the converter, access to that ID is attempted during the bus scan. Asking
the converter to issue INQUIRY commands to itself isn't very polite and
wastes time. Set this_id to 7 so __scsi_scan_target() skips it in the scan.
2. Enable multi-LUN support. eUSCSI devices don't support Get Max LUN
requests, returning an error (-32). [Different targets could have different
numbers of LUNs, so it wouldn't make sense to return a particular value in
response to Get Max LUN.]
usb_stor_scan_dwork() does this:
/* For bulk-only devices, determine the max LUN value */
if (us->protocol == USB_PR_BULK && !(us->fflags & US_FL_SINGLE_LUN)) {
mutex_lock(&us->dev_mutex);
us->max_lun = usb_stor_Bulk_max_lun(us);
mutex_unlock(&us->dev_mutex);
It avoids calling usb_stor_Bulk_max_lun() if US_FL_SINGLE_LUN, but not for
US_FL_SCM_MULT_TARG. Since usb_stor_Bulk_max_lun() returns 0 in the error
case, us->max_lun was always set to 0.
[If the user doesn't want multi-LUN support (perhaps there are SCSI devices
which respond to commands on all LUNs?), the US_FL_SINGLE_LUN quirk can be
specified on the kernel command line.]

Remove the tagged argument from scsi_adjust_queue_depth, and just let it
handle the queue depth. For most drivers those two are fairly separate,
given that most modern drivers don't care about the SCSI "tagged" status
of a command at all, and many old drivers allow queuing of multiple
untagged commands in the driver.
Instead we start out with the ->simple_tags flag set before calling
->slave_configure, which is how all drivers actually looking at
->simple_tags except for one worke anyway. The one other case looks
broken, but I've kept the behavior as-is for now.
Except for that we only change ->simple_tags from the ->change_queue_type,
and when rejecting a tag message in a single driver, so keeping this
churn out of scsi_adjust_queue_depth is a clear win.
Now that the usage of scsi_adjust_queue_depth is more obvious we can
also remove all the trivial instances in ->slave_alloc or ->slave_configure
that just set it to the cmd_per_lun default.

Currently scsi piggy backs on the block layer to define the concept
of a tagged command. But we want to be able to have block-level host-wide
tags assigned even for untagged commands like the initial INQUIRY, so add
a new SCSI-level flag for commands that are tagged at the scsi level, so
that even commands without that set can have tags assigned to them. Note
that this alredy is the case for the blk-mq code path, and this just lets
the old path catch up with it.
We also set this flag based upon sdev->simple_tags instead of the block
queue flag, so that it is entirely independent of the block layer tagging,
and thus always correct even if a driver doesn't use block level tagging
yet.
Also remove the old blk_rq_tagged; it was only used by SCSI drivers, and
removing it forces them to look for the proper replacement.

Some mass storage devices return a bogus value in response to a Get Max LUN
request. The Iomega Jaz USB Adapter responds with 0x10, hence my recent
patch to use the US_FL_SINGLE_LUN quirk for it.
The USB MSC Bulk Only Transport document says "The device shall return one
byte of data that contains the maximum LUN supported by the device."
Since the LUN field in the command block wrapper is only 4 bits wide, it
might be helpful to report too-large LUN values in the kernel log, and
assume max LUN is actually 0. That could get some devices which currently
need the US_FL_SINGLE_LUN quirk to work.

With uas over usb-3 the tags inside the uas iu-s must match the usb-3 stream
ids, and those go from 1 - qdepth.
Before blk-mq calling scsi_activate_tcq(sdev, qdepth) guaranteed that we would
only get cmnd->request->tag from 0 - (qdepth - 1), and we used those as
uas-tags / stream-ids.
With blk-mq however we are guaranteed to never get more then qdepth commands
queued at the same time, but the cmnd->request->tag values may be much larger,
which breaks uas.
This commit fixes this by generating uas tags in the 1 - qdepth range ourselves
instead of using cmnd->request->tag.
While touching all involved code anyways also rename the uas_cmd_info stream
field to uas_tag, because when using uas over usb-2 streams are not used.

Sometimes mass-storage devices using the Bulk-only transport will
mistakenly skip the data phase of a command. Rather than sending the
data expected by the host or sending a zero-length packet, they go
directly to the status phase and send the CSW.
This causes problems for usb-storage, for obvious reasons. The driver
will interpret the CSW as a short data transfer and will wait to
receive a CSW. The device won't have anything left to send, so the
command eventually times out.
The SCSI layer doesn't retry commands after they time out (this is a
relatively recent change). Therefore we should do our best to detect
a skipped data phase and handle it promptly.
This patch adds code to do that. If usb-storage receives a short
13-byte data transfer from the device, and if the first four bytes of
the data match the CSW signature, the driver will set the residue to
the full transfer length and interpret the data as a CSW.
This fixes Bugzilla #86611.

[SCSI] uas: disable use of blk-mq I/O path
[SCSI] cxgb4i: avoid holding mutex in interrupt context
The stream_id and pipe are already present in uas_cmd_info resp uas_dev_info,
so there is no need to pass a copy along.

The uas driver uses the block layer tag for USB3 stream IDs. With
blk-mq we can get larger tag numbers that the queue depth, which breaks
this assumption. A fix is under way for 3.18, but sits on top of
large changes so can't easily be backported. Set the disable_blk_mq
path so that a uas device can't easily crash the system when using
blk-mq for SCSI.

There is apparently another SCM USB-SCSI converter with ID 04E6:000F. It
is listed along with 04E6:000B in the Windows INF file for the Startech
ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)". The quirk allows
devices with SCSI ID other than 0 to be accessed.
Also make a couple of existing SCM product IDs lower case to be
consistent with other entries.

Castlewood Systems supplied various models of USB-SCSI converter with their
ORB external removable-media drive. The ORB Windows and Macintosh drivers
support six USB IDs:
084B:A001 [VID 084B is Castlewood Systems]
04E6:0002 (*) ORB USB Smart Cable P/N 88205-001 (generic SCM ID)
2027:A001 Double-H Technology DH-2000SC
1822:0001 (*) Ariston iConnect/iSCSI
07AF:0004 (*) Microtech XpressSCSI (25-pin)
07AF:0005 (*) Microtech XpressSCSI (50-pin)
*: quirk already in unusual-devs.h
[Apparently the official VID for Double-H Technology is 0x07EB = 2027
decimal. That's another hex/decimal mix-up with these SCM-based products
(in addition to the Ariston and Entrega ones). Perhaps the USB-IF informed
companies of their allocated VID in decimal, but they assumed it was hex?
It seems all Entrega products used VID 0x1645, not just the USB-SCSI
converter.]
Double-H Technology Co., Ltd. produced a USB-SCSI converter, model
DH-2000SC, which is probably the one supported by the ORB drivers. Perhaps
the Castlewood-bundled product had a different label or PID though?
Castlewood mentioned Conmate as being one type of USB-SCSI converter.
Conmate and Double-H seem related somehow; both company addresses in the
same road, and at one point the Conmate web site mentioned DH-2000H4,
DH-200D4/DH-2000C4 as models of USB hub (DH short for Double-H presumably).
Conmate did show a USB-SCSI converter model CM-660 on their web site at one
point. My guess is that was identical to the DH-2000SC.
Mention of the Double-H product:
http://web.archive.org/web/20010221010141/http://www.doubleh.com.tw/dh-2000sc.htm
The only picture I could find is at
http://jp.acesuppliers.com/catalog/j64/component/page03.html
The casing design looks the same as my ORB USB Smart Cable which has ID
04E6:0002.
Anyway, that's enough rambling. Here's the patch.
storage: Add quirks for Castlewood and Double-H USB-SCSI converters
Add quirks for two SCM-based USB-SCSI converters which were bundled with
some Castlewood ORB removable drives. Without the quirk only the (single)
drive with SCSI ID 0 can be accessed.

usb_stor_euscsi_init() calls usb_stor_control_msg() with timeout
argument 5000. USB_CTRL_SET_TIMEOUT is defined to be 5000 in usb.h, so
would it make sense to use that instead? Patch below if it would.
