The 7023 product id is the generic product id for the Etron EJ168, it is
not specific to the version found on the Asrock P67 motherboard. The same id
is e.g. also used on Gigabyte motherboards and on no-name pci-e usb-3 addon
cards.

Streams on the EJ168 do not work as they should. I've spend 2 days trying
to get them to work, but without success.
The first problem is that when ever you ring the stream-ring doorbell, the
controller starts executing trbs at the beginning of the first ring segment,
event if it ended somewhere else previously. This can be worked around by
allowing enqueing only one td (not a problem with how streams are typically
used) and then resetting our copies of the enqueueing en dequeueing pointers
on a td completion to match what the controller seems to be doing.
This way things seem to start working with uas and instead of being able
to complete only the very first scsi command, the scsi core can probe the disk.
But then things break later on when td-s get enqueued with more then one
trb. The controller does seem to increase its dequeue pointer while executing
a stream-ring (data transfer events I inserted for debugging do trigger).
However execution seems to stop at the final normal trb of a multi trb td,
even if there is a data transfer event inserted after the final trb.
The first problem alone is a serious deviation from the spec, and esp.
dealing with cancellation would have been very tricky if not outright
impossible, but the second problem simply is a deal breaker altogether,
so this patch simply disables streams.
Note this will cause the usb-storage + uas driver pair to automatically switch
to using usb-storage instead of uas on these devices, essentially reverting
to the 3.14 and earlier behavior when uas was marked CONFIG_BROKEN.

Some jmicron uas chipsets act up (they disconnect from the bus) when sending
more then 32 commands to them at once.
Rather then building an ever growing list with usb-id based quirks for
devices using this chipset, simply reduce the qdepth to 32 when connected
over usb-2. 32 should be plenty to keep things close to maximum
possible throughput on usb-2.

Correct typo in the name of the type given to sizeof. Because it is the

This patch adds a usb quirk to support devices with interupt endpoints
and bInterval values expressed as microframes. The quirk causes the
parse endpoint function to modify the reported bInterval to a standards
conforming value.
There is currently code in the endpoint parser that checks for
bIntervals that are outside of the valid range (1-16 for USB 2+ high
speed and super speed interupt endpoints). In this case, the code assumes
the bInterval is being reported in 1ms frames. As well, the correction
is only applied if the original bInterval value is out of the 1-16 range.
With this quirk applied to the device, the bInterval will be
accurately adjusted from microframes to an exponent.

As per Ian, at this point in time it is not worth implementing an async
command interface for diagnostic interrupts for this board. As this is
the case, this patch removes the code which supports such interrupts as it
is now unused.
This includes removing apci1564_do_read(), which was the insn_read
operation for the digital output subdevice, since all it was doing was
reading the current diagnostic interrupt type and returning it in 'data'.
This doesn't follow the comedi API and this operation can be emulated by
the comedi core anyway since the insn_bits operation follows the comedi
API. So it is safe to simply remove this function.

This board provides VCC/CC diagnostic information, and it also supports
diagnostic interrupts. However, as per Ian, these interrupts aren't very
useful and it is enough to simply provide an interface for accessing the
diagnostic status on-demand. This patch adds a 2-channel digital input
subdevice with an insn_bits handler to access this information.

The "ii_pci20kc" module is a comedi driver for Intelligent Instruments
PCI-20001C carrier board and modules. Despite the name, this is
actually an ISA board and uses 1K of ISA memory space (below 1M) for the
main board plus up to three modules. The address is set by hardware
jumpers.
When the board is attached to Comedi via the `COMEDI_DEVCONFIG` ioctl
and the driver's legacy "attach" handler, the base address is passed in.
The driver currently uses that address as-is, which is a bad idea. It
doesn't even reserve the memory region.
Fix that by sanity checking the passed in address, reserving the memory
region and ioremapping it.
Replace the current "detach" handler `comedi_legacy_detach()` with a new
handler `ii20k_detach()` which unmaps the memory and releases the
region.

nr_dirty is updated without locking, causing it to drift so that it is
non-zero (either a small positive integer, or a very large one when an
underflow occurs) even when there are no actual dirty blocks. This was
due to a race between the workqueue and map function accessing nr_dirty
in parallel without proper protection.
People were seeing under runs due to a race on increment/decrement of
nr_dirty, see: https://lkml.org/lkml/2014/6/3/648
Fix this by using an atomic_t for nr_dirty.

1d3d4437eae1 ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled. The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags. So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).
Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.
This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once. This has been broken since 3.12.
