✨ vfree_atomic(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the vfree_atomic(9) page and it's lowkey iconic for how short it is 💅

🌸 NAME 🌸

vfree_atomic — release memory allocated by vmalloc()

---

🎀 SYNOPSIS 🎀

void vfree_atomic (const void *addr );

---

🦋 ARGUMENTS 🦋

• addr — the memory base address 🫶 (that's it, that's the whole argument, she's simple and she knows it)

---

💖 DESCRIPTION 💖

So this one is literally just like vfree, no cap — the only glow-up is that you can call it from any atomic context 🌈

⚠️ except NMIs. Not NMIs. Never NMIs. She said what she said 💀
