 *   - The $GIT_DIR/index
 *   - dir_struct flags

 *   - 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
