Significance of spacing in linear_conf_t

[Sandeep K Sinha <sandeepksinha@xxxxxxxxx>]

Hi,
Can someone help me understand the significance of spacing in struct linear_conf_t ?

struct linear_private_data
{
    struct linear_private_data *prev;   /* earlier version */
    dev_info_t      **hash_table;
    sector_t        spacing;
    sector_t        array_sectors;
    int         sector_shift;   /* shift before dividing
                         * by spacing
                         */
    dev_info_t      disks[0];
};
