HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

European Comission Funding the work done by the University of Helsinki SysKonnect Loan of FDDI and Gigabit Ethernet cards ASUSTeK Loan of I2O motherboard STATUS: o The core setup works within limits. o The scsi layer seems to almost work. I'm still chasing down the hang bug. o The block OSM is mostly functional o LAN OSM works with FDDI and Ethernet cards. TO DO: General: o Provide hidden address space if asked o Long term message flow control o PCI IOP's without interrupts are not supported yet o Push FAIL handling into the core o DDM control interfaces for module load etc o Add I2O 2.0 support (Deffered to 2.5 kernel) Block: o Multiple major numbers o Read ahead and cache handling stuff. Talk to Ingo and people o Power management o Finish Media changers SCSI: o Find the right way to associate drives/luns/busses Lan: o Performance tuning o Test Fibre Channel code Tape: o Anyone seen anything implementing this ? (D.S: Will attempt to do so if spare cycles permit)
