💅 vgic_v3_rdist_overlap — a lil vibe check for your redistributor regions

okay so bestie, this is a page from the Kernel API Manual, and it's about vgic_v3_rdist_overlap(9) — literally the function you call when you need to know if a region you're about to place is gonna crash the party that is an existing redistributor region 🎀

Think of it as the bouncer at the door checking the guest list: "is this spot already taken or what?"
