      [PATCH] usbcore misc cleanup · 846f917c
      David Brownell authored
      This has minor usbcore cleanups:
      
      DOC:
          - the changes passing a usb_interface to driver probe() and disconnect()
            weren't reflected in their adjacent docs.  likewise they still said
            it was possible to get a null usb_device_id (no more).
      
          - the (root) hub API restrictions from rmk's ARM patch weren't
            flagged
      
          - mention the non-dma-coherent cache issue for usb_buffer_alloc()
      
          - mention disconnect() cleanup issue with usb_{control,bulk}_msg()
            [ you can't cancel those urbs from disconnect() ]
      
      CODE
          - make driver ioctl() use 'usb_interface' too ... this update
            also resolves an old 'one instance per device' bad assumption
      
          - module locking on driver->ioctl() was goofy, kept BKL way too
            long and didn't try_inc_mod_count() like the rest of usbcore
      
          - hcd unlink code treated iso inappropriately like interrupt;
            only interrupt still wants that automagic mode
      
          - move iso init out of ohci into shared submit_urb logic
      
          - remove interrupt transfer length restriction; hcds that don't
            handle packetization (just like bulk :) should be updated,
            but device drivers won't care for now.

      driver core: added location of device in driverfs tree to /sbin/hotplug call. · c422d217
      Greg Kroah-Hartman authored
      /sbin/hotplug is now called when any device is added or removed from the
      system.

      [PATCH] Remove QDIO_BH · 06ccf012
      Matthew Wilcox authored
      QDIO_BH was never actually used anyway, and won't do much good now BHs
      are gone.

      [PATCH] alloc_disk/put_disk · 2e26b412
      Alexander Viro authored
      Beginning of proper refcounting.  New helpers introduced, several drivers
      switched to using them for dynamic allocation of gendisks.  Once everything
      is switched (and that will be way easier than per-drive gendisks series)
      we will be able to add sane reference counts on gendisk, at which point
      we can safely put pointer to gendisk in struct block_device / struct request
      and we had pretty much won - from that point it's pretty straightforward
      crapectomy in drivers.

      [PATCH] ->major_name inlined · db5605b2
      Alexander Viro authored
      char *major_name replaced with char disk_name[16];  All uses of ->major_name
      replaced with those of ->disk_name and (obviously) simplified big way.  Bunch
      of arrays, kmallocs, etc. is gone.

      [PATCH] register_disk() unexported · 14cad666
      Alexander Viro authored
      ... now it can be done.  We also drop almost all arguments - there is only
      one caller and everything is determined by the first argument.

      [PATCH] ubd fixes · 09d9ea9b

      Cleans the handling of partitioning up.  More or less the same story as with
      other drivers...

      [PATCH] get_gendisk() prototype change · 02bf8fda
      Alexander Viro authored
      get_gendisk() now takes dev_t (instead of kdev_t) and gets an additional
      argument - int *part.  Set to 0 for non-partitioned, partition number
      for partititoned.  Callers updated.  Yes, I hate passing return values
      that way ;-/  We need that since old "minor(dev) - disk->first_minor"
      doesn't work for stuff with non-trivial numbers (e.g. floppy) and
      get_gendisk() really has to return both gendisk and partition number.
      Fortunately, amount of callers of gendisk() is about to drop RSN big way...

      [PATCH] gendisks list switched to list_head · 780ad0f4
      Alexander Viro authored
      The list used to generate /proc/partitions turned into list_head one;
      we also restore the old order of elements (originally we added to the end
      of list; recent changes had reverted that, now we are back to original
      order).

      [PATCH] raid5 BIO_UPTODATE set · ae5f1b4f
      Jens Axboe authored
      These days we only require a clear of BIO_UPTODATE on -EIO, we don't set
      it on success. This breaks raid5. It appears to clear BIO_UPTODATE fine
      but doesn't start out with it set.

      [PATCH] make loop set right queue restrictions · 8261c271
      Jens Axboe authored
      This makes loop honor the queue restrictions by basically stacking all
      of those, and mirroring the merge_bvec_fn() on the target queue. It also
      switches loop to use per-loop device queues, since that is the only sane
      way to do this from a performance POV. Also, in principle I find it to
      be much nicer if every distinct block device has its own queue.

      [PATCH] don't BUG() on too big a bio · cc27d75d
      Jens Axboe authored
      There's really no reason to BUG() out on a bio that is too big, the
      gentleman thing to do would be to print a warning and just end the bio
      with -EIO quietly.

      [PATCH] request_irq() use GFP_ATOMIC · 88a745f5
      Jens Axboe authored
      The might_sleep() thing caught ide, which calls request_irq() with a
      lock held. It can be argued that this is a bad thing, however I think it
      can also validly be argued that requesting an irq should not be a
      blocking operation. This might even remove some driver bugs where usage
      count is not incremented during init...
      
      It can also be argued, that the very first irq requests cannot be
      blocking for io anyways, for good reason :-)

      [PATCH] sigfix-2.5.39-D0, BK-curr · 5b5a877d
      Ingo Molnar authored
      This fixes a procfs crash noticed by Anton Blanchard.
      
      The procfs code can have a reference even to an already exited task, so
      it needs to follow special rules accessing p->sig.  The atomic-signals
      patch made this bug happen at a much higher frequency, but procfs i
      believe was buggy ever since, it potentially used the freed signal
      structure - which just did not result in a crash like it does today.
      
      The proper fix is to take the tasklist read-lock in
      collect_sigign_sigcatch(), this excludes __exit_sighand() freeing the
      signal structure prematurely.
