Um, what? There's no way this doesn't break the ABI. You do have spare
bytes in the struct, but to use them, you have to add an 'unsigned short'
between dev_fn and board_id:
typedef struct _cciss_pci_info_struct
{
unsigned char bus;
unsigned char dev_fn;
+ unsigned int domain;
__u32 board_id;
}

himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
