💅 panthor_vm_as — the manual page, but make it make sense

okay so bestie, quick vibe check: this is a Kernel API Manual page for panthor_vm_as(9). Yes, a kernel function with a manual page. She's mainstream like that. 🎀

✨ NAME ✨

panthor_vm_as — get the AS slot attached to a VM 🫶

like, the whole entire job of this function is fetching that slot for you. that's it. that's the gig.

---

🌸 SYNOPSIS 🌸

int panthor_vm_as (struct panthor_vm *vm );

one function, one argument, one return value. lowkey elegant, honestly. 👑

---

🦋 ARGUMENTS 🦋

• vm — the VM you want the AS slot of. the VM in question. the main character VM, if you will. 💖

---

⭐ RETURN ⭐

• -1 — if the VM hasn't been assigned an AS slot yet. no slot, no vibe, bestie. 😭

fr fr: -1 is the "not yet" answer and anything >= 0 is the "we're so back" answer.
