netmem_ref(9)

🎀 NAME 🎀

okay so welcome to netmem_ref(9), straight from the Kernel API Manual, bestie! 💖 This is typedef netmem_ref — and yes, it's a nonexistent type whose whole main-character job is marking a reference to generic network memory. It's giving "I literally don't exist as a type" energy, no cap. ✨💅

🦋 Description 🦋

A netmem_ref can be a struct page* or a struct net_iov* underneath — like, it's got layers, okay? 👀💅

Use the supplied helpers to obtain the underlying memory pointer and fields, periodt. That's the assignment, bestie. 🫶
