trace_sched...k_queue_work(9)

✨ trace_sched...k_queue_work(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual, and honestly? it's a short one, but it's iconic. it's about a tracepoint. a tracepoint. the little "hey, something happened!" wink the kernel gives you. let's get into it 🫶

---

🎀 NAME 🎀

trace_sched_kthread_work_queue_work — the function that gets called when a work gets queued 💅

like, literally, that's the whole thing. that's the name. no cap.

---

🌸 SYNOPSIS 🌸

void trace_sched_kthread_work_queue_work (struct kthread_worker *worker
, struct kthread_work *work );

that's the whole signature, copy-pasted exactly, character for character, because we do not mess with code in this house 🙈

---

🦋 ARGUMENTS 🦋

• worker — pointer to the kthread_worker. like, the actual worker thread thing that's doing the work. that's the one 🧚
• work — pointer to struct kthread_work. the unit of work itself, chillin' in struct form ✨

two args. that's it. that's the whole lineup. two little pointers out here doing main character energy 👑

---

💜 DESCRIPTION 💜

so here's the vibe: this event fires when a work is queued. and the details matter, so listen up 🙈

it occurs when a work is queued immediately, or once a delayed work is actually queued — and yes, that means once the delay has been reached, i.e. once the waiting is done and the work is for real actually queued. ie: once the delay has been reached. fr fr, keep that part 💅

so like… not when you schedule the delay. when the delay ends. big difference. lowkey important. ⭐

---

🔥 SEE ALSO 🔥

• Kernel file ./include/trace/events/sched.h — that's where the magic lives, go look at it, it's giving source-of-truth 🌈
• trace_sched_kthread_work_execute_start(9)
• trace_sched_kthread_work_execute_end(9)
• trace_sched_prepare_exec(9)

all the siblings. the whole little tracepoint family. obsessed 💖

---

bestie reminder: this page is literally just describing a tracepoint wrapper, so don't go inventing behaviour for it. it fires, it traces, it slays. periodt ✨

---

and that's the page! 🎀 credit where it's due: it comes from ./include/trace/events, dated October 2026, and the footer reprints the header as trace_sched...k_queue_work(9) — same energy at both ends, we love a symmetric icon 💅🫶 bye bestie!
