don't go away when the kernel is compiled with -O. The functions are backed up by extern versions in cd9660_util.c, but these versions are disabled by `#ifdef __notanymore__'. They could have been enabled by using `#if defined(__notanymore__) || !defined(__OPTIMIZE__)' but then I would have had to check that they still work. The correct way to handle all this is to replace `extern inline' by `EXTERN_INLINE' and define `EXTERN_INLINE' as `extern inline' in most modules and as empty in one module.
