xe_bo_free(9)

💖 xe_bo_free(9) — the kernel API manual, bestie edition 💖

okay so welcome to xe_bo_free(9), straight out of the Kernel API Manual, and honestly? this one's short and sweet. it's the cleanup girlie of the xe_bo family 🎀

---

✨ NAME ✨

xe_bo_free — frees up storage that was allocated with xe_bo_alloc() 🗑️✨

like, you know how xe_bo_alloc() hands you a buffer object and you're all "omg thank you"? yeah, this is the part where you give it back. balanced. iconic. no cap 💅

---

🦋 SYNOPSIS 🦋

void xe_bo_free (struct xe_bo *bo );

returns nothing (void), takes exactly one thing, and that one thing is the bo. that's the whole vibe check 🌸

---

🌈 ARGUMENTS 🌈

• bo — the buffer object storage 🫶 this is the thing you're freeing, the main character of the whole operation tbh

---

⭐ DESCRIPTION ⭐

here's the tea: the actual valid use-cases live in the xe_bo_alloc documentation 📖 so if you're like "wait, when am I even allowed to do this??" — go read that one first, bestie. this page is not the lore drop for that, it's genuinely just pointing you at the right page. iykyk 💜
