__account_scheduler_latency(9)

💅 __account_scheduler_latency — like, the whole vibe

okay so bestie, we're in the Kernel API Manual today and this is genuinely a little icon of a function. no cap. let's get into it 🫶

---

✨ NAME ✨

__account_scheduler_latency — record an occurred latency ⏱️

---

🎀 SYNOPSIS 🎀

void __account_scheduler_latency (struct task_struct *tsk , int usecs ,
       int inter );

that's it. that's the whole signature. she's small but she's doing something 💅

---

🌸 ARGUMENTS 🌸

• tsk — the task_struct of the task that's hitting the latency. like, whose little vibe check are we recording here 👀
• usecs — how long the latency lasted, in microseconds. yes, micro — she's precise 💖
• inter — 1 if the sleep was interruptible, 0 if it was uninterruptible. pick a lane bestie 🌈

---

🦋 DESCRIPTION 🦋

so this function is the main entry point for recording latency entries — the scheduler is the one calling it, so you know it's main character energy 👑

and listen, she's got a few special cases because normal "non-latency" sleeps are not it:

• interruptible sleep longer than 5 msec gets skipped — lowkey because that's usually just waiting for events via select and co. fake latency, we don't want her 🙈
• negative latencies — caused by time going backwards 😭💀 — are also explicitly skipped. we do not speak of those.

that's the whole deal. she records, she skips the noise, she slays ✨
