+         "Lazy loading" defers loading file details until they are
+         required. This saves mount time, but makes the first look-up
+         a bit longer.
+
+         Lazy loading will only happen if enabled by this option being 'n'
+         and if the appropriate tags are available, else yaffs2 will
+         automatically fall back to immediate loading and do the right
+         thing.
+
+         Lazy laoding will be required by checkpointing.
