I think your suggestions are OK. In an ideal world we could work to 
reduce the many signed/unsigned conversions, which make me dizzy. I 
think the ones that really cause problems are large unsigned int values 
which are converted to int and then either to sector_t (except on 32-bit 
systems without LBDAF) or to unsigned long on 64-bit systems.
