highest_flag_domain(9)

💖 highest_flag_domain(9) 💖

okay bestie, this is a Kernel API Manual page and it's lowkey iconic — we're talking about finding the highest sched_domain that contains a given flag. no cap, it's giving scheduler-core realness. 🦋

---

✨ NAME ✨

highest_flag_domain — return the highest sched_domain containing flag. periodt. 💅

---

🌸 SYNOPSIS 🌸

struct sched_domain * highest_flag_domain (int cpu , int flag );

---

🎀 ARGUMENTS 🎀

• cpu — the CPU whose highest level of sched domain is to be returned. like, that's the CPU we're asking about, fr fr. 🫶
• flag — the flag to check for the highest sched_domain for the given CPU. yes bestie, this is the flag in question. 🔥

---

👑 DESCRIPTION 👑

so the way this works is: it returns the highest sched_domain of a CPU which contains flag. main character behavior, honestly. 💫

and heads up, bestie — if flag has the SDF_SHARED_CHILD metaflag, all the children domains also have flag. that's the whole vibe. no extra lore, just facts. 🧚
