   I think it would be great if originator of this PR tried to mount damaged fs
 ro, found broken directory (I think ino 2 is always the root directory,
 isn't it?), dumped and analyzed it's contents in order to find out how the
 corruption looks like. Then we could at least recreate the result of
 the corruption on test filesystem (by binary editing the media) and
 teach fsck how to cure such corruptions.
