sched_queue_delayed_work(9)

💅 sched_queue_delayed_work(9) — the Kernel API Manual moment

okay so this is sched_queue_delayed_work, and it lives in the Kernel API Manual. yes bestie, we're in kernel land, and this little function is lowkey iconic ✨

---

🌸 NAME

sched_queue_delayed_work — the one that queues up a scheduler delayed work 🎀

---

✨ SYNOPSIS

sched_queue_delayed_work (sched , wname , delay );

like, that's the whole thing. three things in, no drama 🙈

---

🦋 ARGUMENTS

• sched — the scheduler object. literally the main character here 👑
• wname — the work name. it's giving… a name. for the work 💅
• delay — how long the work waits around, measured in jiffies ⏳ (yes, jiffies. that's the unit. no cap.)

---

💜 DESCRIPTION

so here's the vibe: it conditionally queues a scheduler delayed work — but ONLY if there's no reset pending or in-progress. 🚫🔥

read that again, bestie. conditionally. if a reset is pending/in-progress, this thing is not queueing anything. it's just standing there. respectfully. 💀

ngl if you're here you're probably already deep in panthor land. hydrate, take breaks, and don't forget to actually read the reset state before you queue anything 💖
