💅 libeth_xdpsq_lock(9) — Kernel API Manual energy

okay bestie, welcome to the libeth_xdpsq_lock(9) page — yes it's a section 9 kernel API manual, yes we're gonna make it cute, and no we are not skipping a single line of it. grab a boba, this one's short but iconic 🎀

---

✨ NAME ✨

libeth_xdpsq_lock — grab &libeth_xdpsq_lock if needed 🫶

like, only if needed, that's the whole personality of this function ngl

---

🌸 SYNOPSIS 🌸

void libeth_xdpsq_lock (struct libeth_xdpsq_lock *lock );

that's it. one argument. she's lowkey minimal and we respect it 💅

---

🦋 ARGUMENTS 🦋

• lock — the lock to take, bestie. this is literally the thing you're grabbing 💖

---

👑 DESCRIPTION 👑

so here's the vibe check: this function touches the underlying spinlock — only if the static key is enabled and the queue itself is marked as shareable. 🔥

read that again, because it's the whole tea:

1. static key enabled? ✅ → keep going
2. queue marked shareable? ✅ → now we touch the underlying spinlock
3. either one is a no? → we do not touch it, periodt 💀

it's giving "conditional main character energy" and honestly? slay 🌈
