      [PATCH] USB net drivers, ethtool bus_info · 714c25ed
      David Brownell authored
      USB net drivers, ethtool bus_info
      
      This patch makes the USB network drivers that have ethtool support
      expose only those stable IDs ... no more references to unstable values
      like dev->bus->busnum (changes depending on order of modprobe)
      or dev->devnum (assigned not quite randomly during enumeration :).
      
      This supports more intelligent policies for user mode tools, such
      as "always assign this address to the device on that port", as well
      as making troubleshooting more practical when there are multiple
      devices (of a given type) present ... you can tell which is which.

      [PATCH] USB physical paths id · 3668d7cd
      David Brownell authored
      This provides something that gets discussed regularly: stable
      device IDs.  Straightforward; most of it was already present:
      
          - Moves "bus_name" out of HCD framework into usb_bus.
            This accounts for _by far the bulk_ of this patch, since
            every use of that original field needed to change.
      
          - Make Vojtech's usb_make_path() use bus_name instead
            of unstable bus numbers ... and usb_device->devpath
            instead of recomputing that same info.  Combine two
            stable IDs, and the result is still stable.  And since both
            are precomputed, usb_make_path() turns into only an
            error check wrapped around snprintf() ... so I inlined it.
      
          - Minor tweak to usb_device->devpath construction.  It
            still uses "/" for the root hub (better suggestions?) but
            Vojtech wanted "." for separators, so I changed that.
      
          - The older HCDs (uhci.c etc) initialize usb_bus.bus_name,
            as well as the sharable HCD framework
      
          - HCD framework no longer uses "bus" member.
      
      These IDs are currently exposed in "input" hotplugging, and
      my next patch addresses that for USB network devices.

      This patch is a more complete fix for the device refcount · 99e471c7
      David Brownell authored
      sanity checking and cleanup on device disconnect.
        
          - Splits apart usb_dec_dev_use(), for driver use, and
            usb_free_dev(), for hub/hcd use.  Both now have
            kerneldoc, and will BUG() if the refcount and the
            device tree get out of sync.  (Except for cleanup of
            root hub init errors, refcount must go to zero only
            at the instant disconnect processing completes.)
        
          - More usbcore-internal function declarations are
            now moved out of <linux/usb.h> into hcd.h
        
          - Driver-accessible refcounting is now inlined; minor
            code shrinkage, it's using atomic inc/dec instructions
            not function calls.
      
      <note from greg k-h, there is still some work to be done with USB device
       reference counting, but this patch is a step in the right direction.>

      USB kerneldoc fixes · 3066fa91
      David Brownell authored
      This fixes some kerneldoc bugs for USB.  It catches up with
      the recent rename, and includes a couple minor tweaks/fixes
      I happened to notice.

      [PATCH] usbfs disconnect · b46bff09
      Dan Streetman authored
      This was originally created by David many months ago and posted to the
      list, but not put into the kernel.
      
      I modified the original patch to:
      -patch against the 2.5.7 kernel
      -use the 'real' interface number, not position (to do this I added 2
       methods in usb.c)

      [PATCH] page limit on bulk transfers in usbfs? · a64c6e4b
      Chris Hanson authored
      Here is an updated patch using kmalloc that removes the page limit
      on bulk transfers in usbfs.  I've tested it and it seems to work OK.

      [PATCH] uhci.c FSBR speed problem · 13eac223
      Johannes Erdfelt authored
      The dangers of not ensuring important fields are properly set.
      
      Some, if not all, of the speed problems with uhci.c were caused because
      some important fields were not set and as a result, FSBR was never
      turned on.
      
      This patch also ensures is_suspended is set to 0 properly. This could
      cause some problems suspending the HC when no devices are plugged in.

      [PATCH] uhci.c incorrect locking · dd5c53b9
      Johannes Erdfelt authored
      This fixes a problem that I've not run into and is difficult to trigger,
      but definately a bug. We locked urb->lock, when we meant u->lock. It also
      cleans up the code a little to make it easier to understand and removes
      an obsolete comment.

      [PATCH] uhci.c cleanup · cf81f1c2
      Johannes Erdfelt authored
      This patch merely cleans up the code a little and doesn't fix any bugs.
      It makes a couple of code paths a bit easier to understand, removes an
      unused variable (uhci_list) and some procfs variables when not using
      procfs.

      [PATCH] uhci.c SMP deadlock · 89e62afe
      Johannes Erdfelt authored
      This patch fixes a bug reported by Greg and David, as well as some other
      people recently.
      
      uhci.c would call wait_ms, which can sleep, with spinlocks held. There
      are two places where this happens, but only one was the cause of the
      problem.
