scx_parent(9)

💅 scx_parent(9) — Kernel API Manual

okay bestie, welcome to the scx_parent page ✨ this is one of those tiny little kernel API pages (from the Kernel API Manual, iykyk) that does exactly one thing and does it iconic. let's get into it 🎀

---

🌸 NAME 🌸

scx_parent — find the parent sched, that's it, that's the whole vibe 💖

---

✨ SYNOPSIS ✨

struct scx_sched * scx_parent (struct scx_sched *sch );

like, you hand it a sched and it hands you back the parent. no cap 🫶

---

🦋 ARGUMENTS 🦋

• sch — the sched whose parent you're trying to find 👑 literally just "sched to find the parent of", the assignment is the assignment bestie

---

💫 DESCRIPTION 💫

Returns the parent scheduler 💅 or NULL if sch is root. yeah. that's it. sometimes the simplest lore hits the hardest fr fr 🌈

so if you're at the root?? you get NULL. not a fake parent, not an empty struct, just NULL — main character energy of the null pointer honestly 💀
