			DIRFS IMPLEMENTATION DRAFT

IN-MEMORY NODES (DIRFS NODES)

 struct dirfs node have a pointer to their parent, this way there is no need for
 them to be kept in any data structure (RB-trees, LIST, TAILQ).
 Every dirfs node keeps a refcnt which indicates how many nodes it is parenting
 and the node cannot be destroyed as long as it contains references. One of the
 advantages of having a pointer to the parent is that you can recurse backwards
 and find out the whole path of a node. For dirfs this is extremely useful as
