Comment 2 for bug 441384

The offending bit of code is:

        /*
         * For now, ext4 requires a journal -- but this may change
         * soon if we get that patch from Google. :-)
         */
        if ((sb->s_feature_compat
             & __cpu_to_le32(EXT3_FEATURE_COMPAT_HAS_JOURNAL)) == 0)
                return 0;
