/*
* Partition table and disk geometry handling
*
* A single ioctl with lots of subfunctions:
*
* Device number stuff:
* get_whole_disk() (given the device number of a partition,
* find the device number of the encompassing disk)
* get_all_partitions() (given the device number of a disk, return the
* device numbers of all its known partitions)
*
* Partition stuff:
* add_partition()
* delete_partition()
* test_partition_in_use() (also for test_disk_in_use)
*
* Geometry stuff:
* get_geometry()
* set_geometry()
* get_bios_drivedata()
*
* For today, only the partition stuff - aeb, 990515
