ipc_pcie_kfree_skb(9)

💖 ipc_pcie_kfree_skb — the kernel API manual page (section 9, bestie) 💖

okay so picture this: you're deep in section 9 of the kernel API manual, and you've stumbled onto ipc_pcie_kfree_skb. hiii welcome, come sit with me 🫶 this is the cleanup bestie — the one that frees an skb that was handed to you by ipc_pcie_alloc_*_skb(). that's the whole vibe. allocate responsibly, free responsibly, no leaks, periodt 💅

---

✨ NAME ✨

ipc_pcie_kfree_skb — Free skb allocated by ipc_pcie_alloc_*_skb().

like literally. that's it. that's the job. you got an skb from one of the ipc_pcie_alloc_*_skb() friends, and now you're done with it, so you hand it back. iconic behaviour honestly 🌸

---

🦋 SYNOPSIS 🦋

void ipc_pcie_kfree_skb (struct iosm_pcie *ipc_pcie , struct sk_buff
*skb );

it returns void — nothing comes back, no status code, no receipt, no "thanks bestie". it just... frees. and it takes two things, which we're about to go through 👑

---

🎀 ARGUMENTS 🎀

• ipc_pcie — Pointer to struct iosm_pcie. yes the pointer, the struct itself, the whole situation. 🧚
• skb — Pointer to the skb. the actual skb you want gone. that's the one. 💜

ngl the entire function is two pointers and a dream. but like — pass the right pointers. a wrong pointer here is not a cute look, it's giving undefined chaos 😭
