drm_atomic_commit_put(9)

💅 drm_atomic_commit_put(9) — Kernel API Manual, bestie edition

okay so this is a page from the Kernel API Manual, and it's about drm_atomic_commit_put — yes it's a kernel function, yes it's a 9, yes we're doing this 💖

---

✨ NAME ✨

drm_atomic_commit_put — release a reference to the atomic state 🎀

---

🌸 SYNOPSIS 🌸

void drm_atomic_commit_put (struct drm_atomic_commit *state );

---

🦋 ARGUMENTS 🦋

• state — the atomic state, that's it, that's the whole vibe 💫

---

🧚 DESCRIPTION 🧚

okay so picture this: you're holding a reference to state, and this function releases it. and the moment you drop that final reference? bestie, state gets freed. gone. no cap 😭

the actual slay here is that there's no locking required — none, zero, nada — and you can call it from any context. literally any. iconic behavior honestly 👑

fr fr: the free only happens after the final reference is removed. don't be out here thinking it frees early, that's not the vibe 🙈
