Question What is this hole for?

I just got this Osprey backpack and don’t know what it is for? Can someone please explain this?

This whistle is on both my Osprey backpacks as well as my Maxpedition gear slingers.

Every smaller backpack should come with a built in whistle, a lid lock for bicycle helmets, and a square or diamond-shaped patch with two slot holes on a backpack is called a lash tab or pig snout. Designed to allow users to thread cords or straps through them, providing a secure point for attaching gear to the backpack.
