Interesting, thank you. I stand by my original point, downvotes be damned.

Glad to help out. Here[0] is more information regarding Linux swap space as it relates to processes and the VMM subsystem.

I was wrong in my unconditional assertion that `tmpfs` does not use swap. It can, depending on conditions described here[0].

What I was thinking about is `ramfs`, which does not use/support swap and has other limitations not present in `tmpfs`.

Sorry for confusing the topic.
