napi_is_scheduled(9)

🎀 NAME 🎀

napi_is_scheduled — test if NAPI is scheduled. Bestie, this is the napi_is_scheduled(9) page from the Kernel API Manual, and it's literally just a vibe check for NAPI scheduling 💅✨

---

✨ SYNOPSIS ✨

bool napi_is_scheduled (struct napi_struct *n );

---

🌸 ARGUMENTS 🌸

• n — NAPI context. That's the struct you're checking, bestie 🫶

---

💖 DESCRIPTION 💖

okay so here's the tea ☕: this check is "best-effort". With no locking implemented, a NAPI can be scheduled or terminate right after this check and produce not precise results. So like… don't treat it as a locked-in answer, because it lowkey isn't one 😭

NAPI_STATE_SCHED is an internal state, and napi_is_scheduled should not be used normally — napi_schedule should be used instead. periodt 💅

🚨 Use this only if the driver really needs to check if a NAPI is scheduled — for example, in the context of a delayed timer that can be skipped if a NAPI is already scheduled. iykyk ✨

🦋 RETURN 🦋

True if NAPI is scheduled, False otherwise. That's it, that's the return 🎀
