✨ libeth_xdpsq_init_timer — Kernel API Manual ✨

Okay bestie, gather round 💖 you're looking at libeth_xdpsq_init_timer(9), and yes it's a kernel API manual page, but don't scroll away — this one is actually quick and honestly kind of cute. It does exactly one thing and it does it slay.

---

🌸 NAME 🌸

libeth_xdpsq_init_timer — get that XDPSQ clean-up timer initialized 💅

---

🦋 SYNOPSIS 🦋

void libeth_xdpsq_init_timer (struct libeth_xdpsq_timer *timer , void
*xdpsq , struct libeth_xdpsq_lock *lock , void (*poll)(struct
work_struct *work) );

Four arguments, void return, no drama. Iconic behavior tbh 🔥

---

🎀 ARGUMENTS 🎀

• timer — the timer you're initializing, bestie. This is the main character of the function 💫
• xdpsq — the queue this timer belongs to, i.e. its home base 🏠
• lock — the corresponding XDPSQ lock, so everything stays in sync 🔒
• poll — the queue polling/completion function. Type is void (*poll)(struct work_struct *work) — note that struct work_struct *work parameter, it's literally part of the signature, don't @ me 😌

---

💜 DESCRIPTION 💜

So here's the vibe: XDPSQ clean-up timers must be set up before you use them, at the queue configuration time 📋✨. That's not a suggestion, that's the rules — do it at config time or don't do it at all.

And what does this function actually do? It sets the required pointers and the cleaning callback. That's it. That's the whole thing. Assign, assign, assign, and you're out 🫶

ngl the whole page is like four lines of actual content, so if you got this far you basically already know everything. init your timer at config time, set your pointers, set your callback, periodt 💖
