    Subject[PATCH 06/16] isofs-add-write-bit.diff

    Add %S_IWUGO bit for isofs. Makes it easier to poke on files after
    they have been copied from an ISO-9660 filesystem because they are
    ofte copied in `cp -p` or perhaps `rsync -p` mode.
    They are still not writable though, and isofs will continue to
    correctly return -EROFS for writes.
