igb_free_q_vector(9)

✨ igb_free_q_vector ✨

okay so bestie, welcome to igb_free_q_vector(9) from the Kernel API Manual 💅 this is the cleanup queen of the igb driver and honestly she does exactly one job and does it slayfully.

---

🌸 NAME 🌸

igb_free_q_vector — free the memory that was allocated for a specific interrupt vector 🎀

---

🦋 SYNOPSIS 🦋

void igb_free_q_vector (struct igb_adapter *adapter , int v_idx );

like, that's the whole signature. short. iconic. no notes ✨

---

💖 ARGUMENTS 💖

• adapter — the board private structure to initialize 🫶 (yes that's what the page says, bestie, we're just passing it through)
• v_idx — the index of the vector you want freed 💀 point at the right one please

---

🌈 DESCRIPTION 🌈

This function frees the memory allocated to the q_vector. that's it. that's the whole vibe. she takes the q_vector and she releases it back into the wild 🦋 no cap, one job, done beautifully 👑

lowkey important: this is a free function, so the memory goes bye-bye. don't go using that q_vector afterwards, bestie, that's giving use-after-free energy and we are NOT about that 😭
