✨ svm_range_from_addr(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one's a 9 — yes, a section 9 page, we love a kernel-internals moment 💜 this is svm_range_from_addr, and honestly? it's giving "where's my range" energy.

🌸 NAME 🌸

svm_range_from_addr — find svm range from fault address. literally its whole job 💅

---

🦋 SYNOPSIS 🦋

struct svm_range * svm_range_from_addr (struct svm_range_list *svms ,
unsigned long addr , struct svm_range **parent );

---

🎀 ARGUMENTS 🎀

• svms — the svm range list header, bestie. it's your starting point 🫶
• addr — the address you're searching for in the range interval tree. and no, not in bytes — it's in pages fr fr 📄
• parent — gets you the parent range, but only if the range is on the child list 👑 (iykyk)

---

🔥 CONTEXT 🔥

no cap, the caller must hold svms->lock before calling this. not optional, not a vibe, it's the rule 😭

⭐ RETURN ⭐

returns the svm_range that was found — or NULL if there's nothing there 🙈
