> 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|https://issues.apache.org/jira/browse/HADOOP-1298])
checking along the path, and without requiring the {{INode.parent}} field which could be removed
(see [HADOOP-1687|https://issues.apache.org/jira/browse/HADOOP-1687]).
