I am in a dilemma and want to confirm whether the size of loopback devices is considered while calculation disk size using df -h command.
Here is the output of my df -h command.

As I can see that my total Used space is 204G , but I want to know whether this includes the sizes of the loopback devices or whether the actual Used space on my machine is 204G + (Sum of all loopback devices).
