💅 vmw_bo_dirty_release — a Kernel API Manual moment ✨

okay so bestie, you're in the vmw_bo_dirty_release(9) page, part of the Kernel API Manual, and honestly? It's giving "small function, big cleanup energy." Let's get into it 🫶

---

✨ NAME ✨

vmw_bo_dirty_release — release a dirty-tracking user from a buffer object 🎀

---

🌸 SYNOPSIS 🌸

void vmw_bo_dirty_release (struct vmw_bo *vbo );

Not me screaming, it's literally one argument. Main character simplicity 💅

---

🦋 ARGUMENTS 🦋

• vbo — the buffer object. That's it, that's the whole vibe. 👑

---

🔥 DESCRIPTION 🔥

So here's the tea: this function releases a dirty-tracking user from a buffer object. Periodt.

And lowkey the important part — if the reference count reaches zero, then the dirty-tracking object gets freed and the pointer to it cleared. So like, last one out turns off the lights, bestie 💀✨

---

🌈 RETURN 🌈

• Zero on success 🎉
• -ENOMEM on memory allocation failure 😭

(Yes, the page says the function returns void in the synopsis and then tells you about return values — we don't question the lore, we just report it faithfully, iykyk 🙈)
