Description

This patch introduces INode[] INodeDirectory.getExistingPathINodes(String path), modeled over the existing getNode() / getINode().
The purpose of this is to provide a way to retrieve all existing INodes in a path in a single tree scan.
This to allow fast INode's permission (see HADOOP-1298) checking along the path, and without requiring the INode.parent field which could be removed (see HADOOP-1687).
