This patch adds the vstusb driver to the drivers/usb/misc directory.
This driver provides support for Vernier Software & Technology
spectrometers, all made by Ocean Optics. The driver provides both IOCTL
and read()/write() methods for sending raw data to spectrometers across
the bulk channel. Each method allows for a configured timeout.

Add a new mechanism to the composite gadget framework, letting
functions deactivate (and reactivate) themselves. Think of it
as a refcounted wrapper for the software pullup control.
A key example of why to use this mechanism involves functions that
require a userspace daemon. Those functions shuld use this new
mechanism to prevent the gadget from enumerating until those daemons
are activated. Without this mechanism, hosts would see devices that
malfunction until the relevant daemons start.

looking at usb_kill_urb() it seems to me that it is unnecessarily lenient.
In the use case of disconnect() you never want to use the URB again
(for the same device) But leaving urb->reject elevated will make it easier

This fixes the bug reported by Nikanth Karthikesan <knikanth@suse.de>:
http://lkml.org/lkml/2008/10/2/203
The root cause of the bug is that blk_phys_contig_segment
miscalculates q->max_segment_size.
blk_phys_contig_segment checks:
req->biotail->bi_size + next_req->bio->bi_size > q->max_segment_size
But blk_recalc_rq_segments might expect that req->biotail and the
previous bio in the req are supposed be merged into one
segment. blk_recalc_rq_segments might also expect that next_req->bio
and the next bio in the next_req are supposed be merged into one
segment. In such case, we merge two requests that can't be merged
here. Later, blk_rq_map_sg gives more segments than it should.
We need to keep track of segment size in blk_recalc_rq_segments and
use it to see if two requests can be merged. This patch implements it
in the similar way that we used to do for hw merging (virtual
merging).

The multiblock allocator needs to be able to release blocks (and issue
a blkdev discard request) when the transaction which freed those
blocks is committed. Previously this was done via a polling mechanism
when blocks are allocated or freed. A much better way of doing things
is to create a jbd2 callback function and attaching the list of blocks
to be freed directly to the transaction structure.
