Subject: Getting HDD serial in kernel space

Hello.

I had a necessity to get HDD serial number in my kernel module.
In user space I can do it so:

    fd = open( "/dev/sda", O_RDONLY|O_NONBLOCK );
    ioctl( fd, HDIO_GET_IDENTITY, &id );
    printf( "Serial: %s", id.serial_no );

How can I do it in kernel space (it is one hdd in machine, plugged with
SATA)?
