wx_free_q_vectors(9)

💅 wx_free_q_vectors(9) 💅

okay so bestie, welcome to wx_free_q_vectors(9) — that's section 9 of the Kernel API Manual, and yes we're in the kernel, so hydrate before you read this 🫶

---

✨ NAME ✨

wx_free_q_vectors — frees the memory that got allocated for the interrupt vectors, no cap 🧹

---

🌸 SYNOPSIS 🌸

void wx_free_q_vectors (struct wx *wx );

literally that's it. one function, one pointer, void return, she's simple and she slays ✨

---

🎀 ARGUMENTS 🎀

• wx — the board private structure you're initializing. that's the whole assignment. give her the struct and she handles the rest 💖

---

🦋 DESCRIPTION 🦋

so what does she actually do? okay:

• She frees the memory allocated to the q_vectors. all of it. bye bye 👋
• In addition — and this is the part people forget — if NAPI is enabled, she deletes any references to the NAPI struct prior to freeing the q_vector. order matters, bestie! references first, then the free. that's the vibe check and she passes every time 🔥

ngl the free path is where bugs hide 🙈 if you skip a reference cleanup, that's a leak or worse — so don't be cute about it, be correct about it 💀
