✨ rcu_dereference_all(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one is short but it's lowkey iconic in its own little way. It's rcu_dereference_all — the all-protected pointer-fetching girlie. Let's get into it 🎀

---

🌸 NAME 🌸

rcu_dereference_all — fetch an RCU-all-protected pointer for dereferencing 🦋

---

⭐ SYNOPSIS ⭐

rcu_dereference_all (p );

no cap, that's the whole vibe ✨

---

🎀 ARGUMENTS 🎀

• p — the pointer you're reading, right before you dereference it. that's her whole job 🫶

---

💖 DESCRIPTION 💖

So basically: rcu_dereference_all makes rcu_dereference_check do the dirty work. that's it. that's the tea ☕ the actual heavy lifting is somebody else's problem, and honestly? we love a delegation moment 👑
