> Currently we use INodeDirectorySnapshottable to represent a snapshottable
> directory. When we set a directory to snapshottable, we also need to replace
> the corresponding INode. It will be better to use a
> DirectorySnapshottableFeature to simplify the process and get rid of the
> inode replacement.
