💖 __in6_dev_stats_get — Kernel API Manual, bestie edition ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> entry for __in6_dev_stats_get(9) and honestly? this one's short and sweet, we love a low-commitment king 👑

🌸 NAME 🌸

__in6_dev_stats_get — get inet6_dev pointer for stats 🎀

like, that's the whole gig. it gets you the inet6_dev pointer. for stats. slay.

---

🦋 SYNOPSIS 🦋

struct inet6_dev * __in6_dev_stats_get (const struct net_device *dev ,
   const struct sk_buff *skb );

look at that signature, it's giving main character energy fr fr 💅

---

✨ ARGUMENTS ✨

• dev — network device 💻 like, the device, the netdev, the whole vibe
• skb — skb for original incoming interface if needed 🌈 so if you need the original incoming interface, this bad boy is where it lives

---

💜 DESCRIPTION 💜

okay so here's the important part, and I need you to actually read it, no skimming 🙈

Caller must hold rcu_read_lock or RTNL, because this function does not take a reference on the inet6_dev.

literally that's it. that's the whole caution. it's an icon of efficiency ✨

so like — the function hands you back an inet6_dev pointer and does not bump a reference on it. meaning if you're not holding rcu_read_lock or RTNL, that pointer could be gone before you finish looking at it. so hold one of them. periodt 💀🔒

the way that this is one (1) sentence of actual technical content and yet the stakes are real — ngl, respect 🫶
