- *  Untracked cache

- *
- *   - The list of files and directories of the directory in question
- *   - The $GIT_DIR/index
- *   - dir_struct flags

- *     from $GIT_WORK_TREE
- *   - The check_only flag in read_directory_recursive (for
- *     DIR_HIDE_EMPTY_DIRECTORIES)
- *
- *  The first input can be checked using directory mtime. In many
- *  filesystems, directory mtime (stat_data field) is updated when its
- *  files or direct subdirs are added or removed.
- *
- *  The second one can be hooked from cache_tree_invalidate_path().
- *  Whenever a file (or a submodule) is added or removed from a
- *  directory, we invalidate that directory.
- *
- *  The remaining inputs are easy, their SHA-1 could be used to verify
- *  their contents (exclude_sha1[], info_exclude_sha1[] and
- *  excludes_file_sha1[])
