* Check if the reserved boot area is in-use. This is called from
* spa_vdev_attach() when adding a device to a raidz vdev, to ensure that the
* reserved area is available as scratch space for raidz expansion.
*
* This function currently always returns 0. On Linux, there are no known

* used when booting to a ZFS root from an MBR partition.
*
* Currently nothing using libzpool can add a disk to a pool, so this does
