From: Aleksandar Markovic <amarkovic@wavecomp.com>

FDFMTBEG, FDFMTTRK, and FDFMTEND ioctls provide means for controlling
formatting of a floppy drive.

FDFMTTRK's third agrument is a pointer to the structure:

struct format_descr {
    unsigned int device,head,track;
};

defined in Linux kernel header <linux/fd.h>.

Since all fields of the structure are of type 'unsigned int', there is
no need to define "target_format_descr".

FDFMTBEG and FDFMTEND ioctls do not use the third argument.
