 * 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
 * external uses of the reserved area. On FreeBSD, the reserved boot area is
 * 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
 * nothing.
