scx_root_protected_live(9)

💅 scx_root_protected_live(9) 💅 — your Kernel API Manual bestie has entered the chat ✨

okay so bestie, this is the Kernel API Manual page for scx_root_protected_live, and it is lowkey iconic for one very specific vibe: paths that only run while the scheduler is live. no cap, it's a tiny little helper and it knows exactly what it's doing 🫶

---

✨ NAME ✨

scx_root_protected_live — root sched for paths that only run while live 🦋

---

🌸 SYNOPSIS 🌸

struct scx_sched * scx_root_protected_live (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments, like literally none, zero, zilch, the void is voiding 🙈

---

💖 DESCRIPTION 💖

okay so here's the tea: scx_root is published before the scheduler goes live, and it is cleared only after the scheduler is fully drained. that means a path that only executes while the scheduler is live can never race an update. periodt. no weird little timing window, no "oops I updated too early" moment, none of that 💅

so this function just returns the root sched with a plain load, and it is never NULL. that's it. that's the whole plot. it's giving "small but trustworthy" energy and honestly? obsessed ✨
