The newly defined ioctl BIODASDCOPYPAIRSWAP takes a structure that
specifies a copy pair that should be swapped. It will call the device
discipline function to perform the swap operation.
The structure looks as followed:
struct dasd_copypair_swap_data_t {
char primary[20];
char secondary[20];
__u8 reserved[64];
};
where primary is the old primary device that will be replaced by the
secondary device. The old primary will become a secondary device
afterwards.
