    That got stamped out. swapon will fail if the file isn't fully
    instantiated on disk:

    static int setup_swap_extents(struct swap_info_struct *sis)
    block = bmap(inode, probe_block + block_in_page);
    if (block == 0)
    goto bad_bmap;

    printk(KERN_ERR "swapon: swapfile has holes\n");
    ret = -EINVAL;
