zap_vma_range(9)

🌸 zap_vma_range(9) — the "nuke this range" girlie of the kernel API manual 🌸

okay so bestie, welcome to zap_vma_range from the Kernel API Manual — this is the (9) section, iykyk 💅

---

✨ SYNOPSIS ✨

void zap_vma_range (struct vm_area_struct *vma , unsigned long address ,
       unsigned long size );

like, the whole thing in one line: you hand it a vma, an address, a size, and it zaps ✨

---

🎀 ARGUMENTS 🎀

• vma — the vma that covers the range you're about to zap, bestie. it's giving "the container of the carnage" 🫶
• address — the starting address of the range to zap. where the zapping begins, periodt 📍
• size — number of bytes to zap. yes, in bytes, not vibes 💀

---

💖 DESCRIPTION 💖

okay so the one rule, the main character rule: the provided address range must be fully contained within vma. like, fully. no half-in-half-out nonsense, no "close enough" 🙈

that's literally it, that's the description, and it ate 🔥

no cap: if your range isn't entirely inside vma, you're not in the vibe check. the manpage says must be fully contained within vma — and we respect the boundaries 💅
