    yes, this does look rather ext2-like ;)

    How long ago was the code cloned from ext2? iirc there have been a
    number of fairly subtle bugs fixed in ext2/dir.c over the past year or
    three. If the code was not quite recently cloned then I'd suggest that
    you spend a bit of time looking through the ext2 changelogs, see if
    there are any bugfixes which needs to be ported.
