Summary of changes from v2.5.41 to v2.5.42
============================================

<Andries.Brouwer@cwi.nl>
        [PATCH] isofs fix
        
        The patch below removes some dead code and nonsense code.
        The part that changes behaviour is
        
         - if (sbi->s_cruft == 'n' &&
         - (volume_seq_no != 0) && (volume_seq_no != 1)) {
         - printk(KERN_WARNING "Warning: defective CD-ROM "
         - "(volume sequence number %d). "
         - "Enabling \"cruft\" mount option.\n", volume_seq_no);
         - sbi->s_cruft = 'y';
         - }
        
        that has already bitten lots of people.
        
        Nothing is wrong with a volume sequence number different from 0 or 1.
        (Cf. Ecma-119.pdf, Sections 4.17, 4.18, 6.6.)
