Umm. No. It's not tmpfs.

tmpfs is a specific ram/swap based filesystem - basically, take enough
4K pages for the size= parameter and do it in memory.  Major user-visible
difference from the older 'ramfs' is that tmpfs pages can move to swap
space, and ramfs pages are nailed down in RAM.

mount -t tmpfs /dev/loop0 /mnt

This never actually looks at /dev/loop0 *at all*.  You could even say this:

mount -t tmpfs none /mnt

and it would work just fine.  Try leaving the '-t tmpfs' off entirely and
let the mount command figure out what type it is, and see if that works
any better for you.
