- * Notes:
- * - if an array is being reshaped (restriped) in order to change the
- * the number of active devices in the array, 'raid_disks' will be
- * the larger of the old and new numbers. 'delta_disks' will
- * be the "new - old". So if +ve, raid_disks is the new value, and
- * "raid_disks-delta_disks" is the old. If -ve, raid_disks is the
- * old value and "raid_disks+delta_disks" is the new (smaller) value.
