      aufs: bugfix, ignore the being freed dynop object · e870e818
      J. R. Okajima authored
      
      
      Aufs DYNOP (Dynamically customizable FS operations) object is managed by
      kref, and when its counter reaches zero, the callback function removes
      the object from the internal list which is protected by a spinlock and
      then frees the object.
      Here there is a small time window between
      A: the counter reaches zero, and
      B: require the lock to remove the object from the list.
      If someone else acquires the lock and searches the list, it may find the
      counter-zero'ed object which means the object is being freed.
      This commit ignores the object whose counter is already zero.
