* File history callback functions called by backup modules. NDMP file history
* supports 2 file history models: path based and inode/directory based.
* Backup/recover modules similar to unix dump/restore utilize the
* inode/directory based model. During the filesystem scan pass,
* ndmpd_file_history_dir() is called. During the file backup pass,
* ndmpd_file_history_node() is called. This model is appropriate for
* modules whose code is structured such that file name and file attribute
* data is not available at the same time. Backup/recover modules similar
* to tar or cpio utilize the path based model. The simple dump/restore module
* included with the SDK uses the path based model.
