    Manfred Spraul authored
    I found several SMP and UP locking errors in usb-storage, attached is a
    patch:
    
    Changes:
    * srb->result is a bitfield, several << 1 were missing.
    * add scsi_lock calls around midlayer calls, release the lock before
      calling usb functions that might sleep.
    * replace the queue semaphore with a queue spinlocks, queuecommand is
      called from bh context.
