I think Paul was going to take it, or at least Geert hinted as such. > > +#define PS3DISK_MAX_DISKS 16 > > +#define PS3DISK_MINORS 16 > > + > > +#define KERNEL_SECTOR_SIZE 512 > > Sigh.

What would be the point of such a helper? I've never seen a need for it. Geert uses it as debug code here, but the fact is that the number of bios in a request is a pretty pointless number. It doesn't tell you anything. There's no 1:1 mapping between bios and segments (or anything else for that matter), so the exercise is purely pointless. -- Jens Axboe _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
