Question The order of the output of virsh guestinfo --filesystem

Hi all.

I'm curious about the output order of virsh guestinfo --filesystem.
Is the output random?

E.g
Guest info
```

[root@localhost ~]# lsblk -Jp -o KNAME,FSTYPE,TYPE,MOUNTPOINT,PKNAME,SERIAL
{
    "blockdevices": [
       {"kname": "/dev/sr0", "fstype": null, "type": "rom", 
"mountpoint": null, "pkname": null, "serial": "drive-scsi0-0-0-0"},
       {"kname": "/dev/vda", "fstype": null, "type": "disk", 
"mountpoint": null, "pkname": null, "serial": null},
       {"kname": "/dev/vda1", "fstype": "vfat", "type": "part", 
"mountpoint": "/boot/efi", "pkname": "/dev/vda", "serial": null},
       {"kname": "/dev/vda2", "fstype": "xfs", "type": "part", 
"mountpoint": "/boot", "pkname": "/dev/vda", "serial": null},
       {"kname": "/dev/vda3", "fstype": "LVM2_member", "type": "part", 
"mountpoint": null, "pkname": "/dev/vda", "serial": null},
       {"kname": "/dev/vdb", "fstype": null, "type": "disk", 
"mountpoint": null, "pkname": null, "serial": null},
       {"kname": "/dev/vdb1", "fstype": "xfs", "type": "part", 
"mountpoint": "/mnt/test1", "pkname": "/dev/vdb", "serial": null},
       {"kname": "/dev/vdb2", "fstype": "xfs", "type": "part", 
"mountpoint": "/mnt/test2", "pkname": "/dev/vdb", "serial": null},
       {"kname": "/dev/vdb3", "fstype": "xfs", "type": "part", 
"mountpoint": "/mnt/test3", "pkname": "/dev/vdb", "serial": null},
       {"kname": "/dev/dm-0", "fstype": "xfs", "type": "lvm", 
"mountpoint": "/", "pkname": "/dev/vda3", "serial": null},
       {"kname": "/dev/dm-1", "fstype": "swap", "type": "lvm", 
"mountpoint": "[SWAP]", "pkname": "/dev/vda3", "serial": null}
    ]
}

```

virsh guestinfo output.
It is not sorted by  name or total-bytes/used-bytes
```
