> 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.
