skb_dst(9)

✨ skb_dst(9) — Kernel API Manual ✨

okay so bestie, welcome to the skb_dst(9) page 💅 this is the Kernel API Manual and honestly this function is a whole mood — tiny, iconic, does exactly one thing, no notes.

---

🌸 NAME 🌸

skb_dst — returns you the skb's dst_entry. that's it. that's the whole job. main character energy but make it a getter 🫶

---

🎀 SYNOPSIS 🎀

struct dst_entry * skb_dst (const struct sk_buff *skb );

---

🦋 ARGUMENTS 🦋

• skb — the buffer, bestie. the one and only thing you pass in 💖

---

💜 RETURN 💜

it gives you back the skb's dst_entry — and ngl, it does not care whether a reference was taken or not. taken ref? not taken? doesn't matter, you get the dst_entry either way. it's giving "i'm not keeping score" 😌✨
