scx_task_sched(9)

💖 NAME 💖

okay so bestie, welcome to scx_task_sched(9) — a page straight out of the Kernel API Manual, and the whole assignment is: Find scx_sched scheduling a task ✨. That’s the vibe, that’s the mission 💅.

⚡ SYNOPSIS ⚡

struct scx_sched * scx_task_sched (const struct task_struct *p );

🎀 ARGUMENTS 🎀

• p — the task of interest 👀. literally the task we’re checking on, no cap.

🌸 DESCRIPTION 🌸

This one returns p’s scheduler instance — like, “who’s scheduling this task?” energy 🕵️‍♀️. But here’s the non-negotiable part, bestie: you must call it with p’s pi_lock or the rq lock held. no cap, that’s the rule. lock it up first, then ask questions 🔒💅.

🦋 SEE ALSO 🦋
