/*
* 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
