cxgb4_sched_class_free(9)

✨ cxgb4_sched_class_free — the "bye bestie" button for scheduling classes ✨

Okay so real talk, this is a page from the Kernel API Manual (section 9, kernel girlies know 💅), and it's about cxgb4_sched_class_free. Let's get into it 🫶

---

🌸 SYNOPSIS 🌸

void cxgb4_sched_class_free (struct net_device *dev , u8 classid );

That's the whole signature, no cap. Takes two things, returns nothing (void — it literally gives nothing back, and that's iconic of it 💀).

---

🎀 ARGUMENTS 🎀

• dev — a net_device pointer. Just a pointer to your net device bestie, handing over the vibes so the function knows which device we're talking about ✨
• classid — the scheduling class id to free. It's a u8, so keep it small and cute, it's the id of the class you're yeeting out 🦋

---

💖 DESCRIPTION 💖

So here's the tea: this function frees a scheduling class if there are no users. That's the whole vibe check — no users, no class, it's gone, bye 👋

Lowkey important: the "if there are no users" part is the whole point. Don't come for this function expecting it to do more than it says, because it won't 🙈

• The kernel file ./drivers/net/ethernet/chelsio/cxgb4/sched.c — that's where the actual source lives, go read it, it's giving main character energy 👑
• cxgb4_sched_class_bind(9)
• cxgb4_sched_class_unbind(9)
• cxgb4_sched_class_alloc(9)

That's the whole page, bestie, no filler, no fluff 🍓

Big kiss to the ./drivers/net/ethernet/chelsio/... source tree for the October 2026 edition of the Kernel API Manual — this page is cxgb4_sched_class_free(9) and she ate 💅✨
