Ok, I found the case. Patch attached.

This cset is update of the HID drivers to the latest version, as a part
of the Input merge. It finally includes ForceFeedback support by Johann
Deneux, enabling ForceFeedback on new Logitech and Microsoft devices.

This patch fixes two problems that have already been discussed
on this list:

- USB_QUEUE_BULK is rather pointless (and UHCI-specific).
   If drivers really want only one bulk urb queued at a time,
   they just shouldn't issue such urbs till others complete.

     FIX:  remove it entirely.

- USB_DISABLE_SPD is horribly named (based on a UHCI flag).
   What it really does is turn non-ISO short reads into errors.

     FIX:  rename it.  Now it's URB_SHORT_NOT_OK.

I changed all the drivers using these two flags, including
corresponding changes in the "usbfs" API.

Most of the patch by volume is doc updates:

- Documentation/usb/URB.txt hadn't been updated in two years (!)
   and was pretty out of date.  It also had many details that were
   inappropriately specific to usb-uhci.
- Most of the URB flags weren't even commented as to intent.
- DISABLE_SPD was often documented as if it were SHORT_IS_OK.
- There was still some doc saying how iso should use urb->next.

There are also some related updates:

- Some of the submit sanity checks for transfer flags were
   overly broad ... SHORT_NOT_OK is only for reads, NO_FSBR
   is for non-periodic requests, ZERO_PACKET only for writes.
- The ohci-hcd code thought SHORT_NOT_OK worked for ISO.
- The uhci-hcd code thought QUEUE_BULK applied to non-bulk

Note that this patch doesn't update any of the "old" HCDs,
including usb-ohci-hcd.

In the case of usb-uhci{,-hcd} it'd have been painful to fix
the QUEUE_BULK logic.  That logic was, I think, the original
reason to have that flag!  So I count switching to "uhci-hcd"
as a win already ... :)

This patch fixes some spelling errors and adds some BUG_ON() calls so we
can make sure that all this new code is working properly.

This patch changes how the exit code works to be cleaner, fixes the OOPS on
rmmod, consolidates some anti-race code from several places to just one,
and also eliminates some theoretical race conditions.

This patch unifies all the bit tests and various flags into a single,
unified system.

Part 2, printk fixups for a the tiglusb and emi26 drivers.

This is the first of a few janitorial fixes for printk() usage in the USB
tree.

Whoever did the strsep patches didn't check that ips still compiles.
here's a patch.

Found a few typos in the input changes. Fixup patch attached.

This fixes a couple issues I noted when I finally spent some time
looking at the first version of driverfs support for usb:

- "name" fields (really descriptions) aren't very useful.

     * for devices, they always said "USB device 0000:0000"
         --> Now they'll only say that when there's
             nothing better to be said ...
         --> ... and it's really device 0000:0000!  It was
             using device descriptor fields before they were
             fetched from the device.
         --> Uses product and/or manufacturer strings, which
             most devices have, much like PCI uses the PCI ID
             database (when it's compiled in)

     * for interfaces, it was "figure out some name..."
         --> Now it combines the strings used in the
             usb_make_path() call with interface number
         --> Or in the remote chance a device provides
             an interface string, that's preferred.
         --> In general, I think the driver for each
             interface is best suited to describe it;
             I modified the hub driver to do so.

- "bus_id" field

     * For hub ports, it was wasting code: we know the port
       already, no need to search for it.  Plus, it used
       0-index ids not the 1-index ones matching physical
       labels on hubs, and other user-visible diagnostics.

     * For interfaces, it mixed the device address with the
       interface number ... producing unstable IDs that were
       moreover rather cryptic.  Changed:  "if0" now, using
       the interface ID (not index).

     * For busses, left "usb_bus" alone ... :)

- Adds two files exposing current configuration (for devices)
   and altsetting (for interfaces).

- I was getting a useless diagnostic from the hub driver,
   now it's less useless (it fully identifies the hub)

  drivers/ide/probe.c initializes gd->de_arr and gd->flags twice. Except that
it is unnecessary it also leaks memory.

Edition 4.1 of the System V Application Binary Interface says that
"The first namesz bytes in name contains a null-terminated
representation of the entry's owner or originator".  This implies that
the terminating null is included in namesz, which is corroborated by
the example that follows the description.  However, this is not what
the Linux kernel does when it writes its notes into an ELF core dump.
The attached patch fixes this.

HACK ALERT! This needs to be fixed to do what reiserfs
actually thinks it _should_ do.

In usb_bluetooth_probe, the transfer buffers for the write pool urbs
are allocated with size 0, because bluetooth->bulk_out_buffer_size isn't set
until after the loop.

Moved the file ops and minor number stuff out of the usb structure,
Now usb_register_dev() and usb_deregister_dev() must be called if 
you want to use the USB major number.

This patch removes BKL protection from the invocation of the
super_operations ->statfs() method, and shifts it into the filesystems
where necessary. Any out-of-tree filesystems may need to take the BKL in
their statfs() methods if they were relying on it for synchronisation.

All ->statfs() implementations have been modified to take the BKL,
except for those that don't reference any external mutable data or that
already have their own locking.

Additionally, capifs is changed to use simple_statfs rather than its
own home-grown version.

The BKL change has been flagged at the end of
Documentation/filesystems/porting, along with the recent change to
->permission BKL usage.

	* ->i_dev followed the example of ->s_dev - it's dev_t now.  All
remaining uses of ->i_dev either outright want dev_t (stat()) or couldn't
care less (printing major:minor in /proc/<pid>/maps, etc.)

	* JFS uses its ->logdev only twice - one of the places assigns
it to_kdev_t(le32_to_cpu(...)), another uses kdev_t_to_nr() of it.
Switched to u32 - it's just a place where we store device number we'd got
from superblock.
	* several reiserfs_fs.h function prototypes removed - functions
in question don't exist anymore.
	* smbfs doesn't support device nodes; ->f_rdev removed.

	* svc_export ->ex_dev turned into dev_t.  It's a pure search
key and all places that set it actually do to_kdev_t(some_dev_t_expression).
