      Description

      Snapshots currently use INodeFile and INodeDirectory for storing previous file/dir states as snapshot inodes. However, INodeFile and INodeDirectory have some fields not used by snapshot inodes such as parent reference, inode id, block/children reference. The memory footprint could be reduced by having some specific classes for snapshot inodes.
