find_vma_intersection(9)

💖 find_vma_intersection(9) 💖

okay bestie, welcome to the Kernel API Manual page for find_vma_intersection — it's giving “look up the first VMA which intersects the interval” energy, and honestly? iconic. 🦋

🌸 NAME 🌸

find_vma_intersection — look up the first VMA which intersects the interval. periodt. 💅

---

✨ SYNOPSIS ✨

struct vm_area_struct * find_vma_intersection (struct mm_struct *mm , unsigned long start_addr , unsigned long end_addr );

---

💅 ARGUMENTS 💅

• mm — the process address space. that's the whole vibe. 🫶
• start_addr — the inclusive start user address. it's included, bestie. 💖
• end_addr — the exclusive end user address. not included, no cap. 🙈

🔥 RETURN 🔥

the first VMA within the provided range, and NULL otherwise. literally that simple. ✨

heads up: this assumes start_addr < end_addr. keep that in mind, okay? 😭

mwah 💋 this little page comes from ./mm, dated October 2026, and it's literally the find_vma_intersection(9) era. bye bestie, slay your VMA lookup 🌈🎀
