+ *
+ * - The list of files and directories of the directory in question
+ * - The $GIT_DIR/index
+ * - dir_struct flags
+ * - The content of $GIT_DIR/info/exclude
+ * - The content of core.excludesfile
+ * - The content (or the lack) of .gitignore of all parent directories
+ * 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
