    OK, it's not exactly clear what you are referring to, but:
    1) On ext3 the superblock is NEVER marked dirty, because of the journal.
    As long as the journal is running normally, the filesystem will always
    be "clean".
    2) There should _not_ be a problem with the needs_recovery flag being set
    from within the kernel. HOWEVER, attempts to read it from user-space
    may fail because of a disconnect between the buffer cache and the page
    cache.

    Now that these issues are in the open (and already being discussed) they
    will likely be fixed in a relatively short timeframe.

    Cheers, Andreas
