> Before supporting rename with snapshots, when adding/remove a child inode
> to/from a directory, if the directory is already an
> INodeDirectoryWithSnapshot, we can directly record the change in the
> corresponding snapshot diff.
> After support rename with snapshots, an INodeDirectoryWithSnapshot may be a
> renamed node, thus we should use INode#isInLatestSnapshot() to check if we
> should record the change in snapshots.
