napi_schedule(9)

💅 napi_schedule(9)

okay so bestie, welcome to another episode of the Kernel API Manual — yes this is the napi_schedule page, the one you keep tabbing to at 2am. let's get into it 🎀

---

✨ NAME ✨

napi_schedule — schedule NAPI poll. that's it. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

bool napi_schedule (struct napi_struct *n );

lowkey the shortest synopsis ever and honestly? slay. 👑

---

🎀 ARGUMENTS 🎀

• n — the NAPI context. your fave struct. the main character of this whole function. 💖

---

💫 DESCRIPTION 💫

so what does it actually do. it schedules the NAPI poll routine to be called — but only if it's not already running. that's the whole deal. no cap.

it's giving "hey bestie, are you up? because if not, we need to run the poll routine." and if you're already up? it's not gonna double-book you. nope. 🙈

---

⭐ RETURN ⭐

it hands back true if we actually schedule a NAPI, and false if not. periodt.

and if you're sitting there like "wait, why not 🥺" — go read napi_schedule_prep, it's got the additional reasons on why a NAPI might not get scheduled. iykyk.
