vm_area_map_pages(9)

💅 vm_area_map_pages(9) — from the Kernel API Manual, bestie ✨

okay so real talk, this one lives in section 9 of the Kernel API Manual and it's all about getting your pages mapped inside a sparse vm_area. no cap, it's a little baddie with a big job 🫶

---

🌸 NAME 🌸

vm_area_map_pages — map pages inside given sparse vm_area 💖

like. literally. that's the whole gig. it takes a sparse vm_area and maps pages inside it. iconic behavior only 👑

---

✨ SYNOPSIS ✨

int vm_area_map_pages (struct vm_struct *area , unsigned long start ,
unsigned long end , struct page **pages );

there she is 😭 four args, returns an int, and yes we are copying it exactly, spaces before the commas and all, because that's just how the page is and we respect it 💅

---

🎀 ARGUMENTS 🎀

• area — the vm_area itself. the main character of this whole situation 🌈
• start — start address inside vm_area. where the mapping begins, bestie 📍
• end — end address inside vm_area. where it stops. the other end. the closing bracket of vibes 🦋
• pages — the pages to map. and heads up: these are always PAGE_SIZE pages — that's just the rule, no exceptions, fr fr 🍓
