💖 vdo_resume_if_quiescent(9) 💖

okay so bestie, we're in the Kernel API Manual today and this one is lowkey a little glow-up function ✨ like it literally takes your admin state from "chill/quiescent" back to "normal operation" energy. it's giving revival arc, it's giving main character returning from the mid-season nap 💅

---

✨ NAME ✨

vdo_resume_if_quiescent — changes the state to normal operation if the current state is quiescent 🦋

like, only if. no cap. it checks first, it's not out here just resuming whenever 🙈

---

🌸 SYNOPSIS 🌸

int vdo_resume_if_quiescent (struct admin_state *state );

that's the whole vibe. one function, one pointer, one int coming back at you 🎀

---

💜 ARGUMENTS 💜

• state — the current admin state 🫶 that's it, that's the whole argument, she's simple and she knows it.

---

🌈 RETURN 🌈

• VDO_SUCCESS — slay, the state resumed, we're so back 👑🔥
• VDO_INVALID_ADMIN_STATE — nope, didn't happen, the state was not quiescent so no resume for you 😭💀
