We need to tie the WUSB and USB devices; the USB stack doesn't need to
know the details about the WUSB device, but needs to have a link to
it. This is needed so that the notify call back for Remove Device can
tie both and undo the device setup (sysfs files).
We connect the devices together at the Add Device notifier callback
(the wusb_dev references the usb_dev and stores it, the usb_dev
references the wusb_dev and stores it); then we do create the WUSB
sysfs files at the usb_dev sysfs directory. At Remove Device, we undo
that (thus we need the usb_dev reference).
Cross reference to functions in the WUSB substack:
wusb_dev_{add,rm}_ncb().

This patch (as1079) cleans up the way URB_* flags are exported in
usbfs.
The URB_NO_INTERRUPT flag is now exported (this is the
only behavioral change).
USBDEVFS_URB_* macros are added for URB_NO_FSBR,
URB_ZERO_PACKET, and URB_NO_INTERRUPT, making explicit the
fact that the kernel accepts them.
The flag matching takes into account that the URB_* values
may change as the kernel evolves, whereas the USBDEVFS_URB_*
values must remain fixed since they are a user API.

I have got a cypress usb-ide bridge and I would like to tune or monitor
my disk with tools like hdparm, hddtemp or smartctl.
My controller support a way to send raw ATA command to the disk with
something call atacb (see
http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf).
Atacb support can be added for each application, but there is some disadvantages :
- all application need to be patched
- A race is possible if there other accesses, because the emulation can
be split in 2 atacb scsi transactions. One for sending the command, one
for reading the register (if ck_cond is set).
I have implemented the emulation in usb-storage with a special proto_handler,
and an unsual entry.

There's a new PM-related change notice for the USB 2.0 specification
called "Link Power Management" (LPM). It defines a new "L1 Suspend"
state which resembles the current (L2) suspend state, except that it
can be entered and exited much more quickly. It should thus be more
useful for runtime PM, even though it doesn't mandate reduced power
draw from VBUS.
This patch provides the relevant #defines for usbcore. Actually
implementing these mechanisms requires host silicon that can generate
new USB packets, plus hubs handling some new requests and peripherals
which understand the new packets.

The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.
Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.
options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.
With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

Add a waitqueue to wait on when there are no buffers in the buffer queue.
DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen.
Once a buffer has been queued we recheck that the queue is still streaming and
wait on the new buffer's waitqueue while holding the vb_lock. The driver
should come along in a timely manner and put the buffer into its next state
finishing the DQBUF.
By implementing this waitqueue it also brings the videobuf DQBUF up to spec and
it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF:
"By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue."

Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.
This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).
At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.
The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.
