usb: storage: unusual_uas: Add JMicron JMS56x to unusual device

2017-01-05T18:24:55+00:00

This device gives the following error on detection.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring

The same error is not seen when it is added to unusual_device
list with US_FL_NO_REPORT_OPCODES passed.

Fix USB CB/CBI storage devices with CONFIG_VMAP_STACK=y

2016-11-15T10:08:51+00:00

Some code (all error handling) submits CDBs that are allocated
on the stack.  This breaks with CB/CBI code that tries to create
URB directly from SCSI command buffer - which happens to be in
vmalloced memory with vmalloced kernel stacks.

Let's make copy of the command in usb_stor_CB_transport.

usb: storage: drop freezer.h usage

2016-11-07T09:19:49+00:00

usb-storage does not use any freezer apis, so drop the inclusion of
freezer.h from the drivers/usb/storage/usb.c file.

scsi: introduce a quirk for false cache reporting

2016-09-13T06:08:24+00:00

Some SATA to USB bridges fail to cooperate with some
drives resulting in no cache being present being reported
to the host. That causes the host to skip sending
a command to synchronize caches. That causes data loss
when the drive is powered down.

usb: storage: fix runtime pm issue in usb_stor_probe2

2016-08-09T13:59:35+00:00

Since commit 71723f95463d "PM / runtime: print error when activating a
child to unactive parent" I see the following error message:

scsi host2: usb-storage 1-3:1.0
scsi host2: runtime PM trying to activate child device host2 but parent
	    (1-3:1.0) is not active

Digging into it it seems to be related to the problem described in the
commit message for cd998ded5c12 "i2c: designware: Prevent runtime
suspend during adapter registration" as scsi_add_host also calls
device_add and after the call to device_add the parent device is
suspended.

Fix this by using the approach from the mentioned commit and getting
the runtime pm reference before calling scsi_add_host.

USB: uas: Fix slave queue_depth not being set

2016-06-01T21:56:24+00:00

Commit 198de51dbc34 ("USB: uas: Limit qdepth at the scsi-host level")
removed the scsi_change_queue_depth() call from uas_slave_configure()
assuming that the slave would inherit the host's queue_depth, which
that commit sets to the same value.

This is incorrect, without the scsi_change_queue_depth() call the slave's
queue_depth defaults to 1, introducing a performance regression.

This commit restores the call, fixing the performance regression.
