> 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.
