      configfs: provide exclusion between IO and removals · b0841eef
      Al Viro authored
      Make sure that attribute methods are not called after the item
      has been removed from the tree.  To do so, we
      	* at the point of no return in removals, grab ->frag_sem
      exclusive and mark the fragment dead.
      	* call the methods of attributes with ->frag_sem taken
      shared and only after having verified that the fragment is still
      alive.
      
      	The main benefit is for method instances - they are
      guaranteed that the objects they are accessing *and* all ancestors
      are still there.  Another win is that we don't need to bother
      with extra refcount on config_item when opening a file -
      the item will be alive for as long as it stays in the tree, and
      we won't touch it/attributes/any associated data after it's
      been removed from the tree.
