	struct block_device * `bdev`,
	sector_t `capacity`,
	int `geom[])`;

Arguments

sdev: SCSI device for which BIOS geometry is to be determined
bdev: block device associated with sdev
capacity: capacity of SCSI device
geom[]: location to which geometry will be output

Description

Generic bios head/sector/cylinder calculator used by sd. Most BIOSes nowadays expect a XXX/255/16 (CHS) mapping. Some situations may arise where the disk is not bootable if this is not used.

LOCKING

Defined by the SCSI layer. We don't really care.
