calculate_imbalance(9)

💅 calculate_imbalance(9) — the kernel API manual, but make it make sense 🎀

okay so bestie, we're in calculate_imbalance(9) territory — that's section 9 of the Kernel API Manual, the one for kernel functions and all that ✨

---

🌸 NAME 🌸

calculate_imbalance — literally does what it says on the tin: it calculates the amount of imbalance present within the groups of a given sched_domain during load balance. no cap, that's the whole vibe check 🔥

---

🦋 SYNOPSIS 🦋

void calculate_imbalance (struct lb_env *env , struct sd_lb_stats *sds );

that's it. two arguments, returns nothing (void), get in, do the math, get out 💅

---

✨ ARGUMENTS ✨

• env — the load balance environment 🌈 — everything the balancing act needs to know about itself lives in here.
• sds — the statistics of the sched_domain whose imbalance is to be calculated 📊 — like, whose vibes are we measuring? this one.

and that's the whole page, bestie — no secrets, no hidden flags, no extra lore, we kept Every Single Detail because that's the rule 💖

this cutie of a page lives under ./kernel/sched, dated October 2026, and it's calculate_imbalance(9) from the Kernel API Manual — go forth and balance those loads, you absolute main character 🧚‍♀️💜
