vma_alloc_ze...ovable_folio(9)

💅 vma_alloc_ze...ovable_folio(9) — the Kernel API Manual, bestie edition 🎀

okay so this is from the Kernel API Manual, section 9 (kernel routines, iykyk), and the page name is literally vma_alloc_ze...ovable_folio(9) — yes it's truncated, no we're not fixing it, it's iconic that way ✨

---

🌸 NAME 🌸

vma_alloc_zeroed_movable_folio — bestie, it allocates a zeroed page for a VMA. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

struct folio * vma_alloc_zeroed_movable_folio (struct vm_area_struct
*vma , unsigned long vaddr );

like, you hand it a VMA and a vaddr and it gives you back a struct folio *. simple. clean. slay. 💅

---

🦋 ARGUMENTS 🦋

• vma — the VMA the page is gonna be allocated for. it's giving "here's the neighborhood, find me a house" 🏡
• vaddr — the virtual address the page will be inserted into. this is the exact spot, no cap 📍

---

💖 DESCRIPTION 💖

so this function will allocate a page suitable for inserting into this VMA at this virtual address. literally that's it, that's the job. 💀

it may be allocated from highmem or the movable zone — highkey depends on the situation, we don't gatekeep. and bestie, important detail: an architecture may provide its own implementation. so like, your arch might have main character energy and do its own thing. don't @ me. 👑

---

⭐ RETURN ⭐

you get a folio containing one allocated and zeroed page 🎀 …or NULL if we are out of memory 😭 (yes, the OOM jumpscare is real, no cap).
