workqueue_set_min_active(9)

💅 workqueue_set_min_active(9) — Kernel API Manual energy ✨

Hey bestie 💖 you're looking at workqueue_set_min_active(9) from the Kernel API Manual. Manual name folded in, vibe check passed, let's get into the workqueue lore. 🦋

---

🌸 NAME 🌸

workqueue_set_min_active — adjust min_active of an unbound workqueue. That's the name, no cap. 💅

---

✨ SYNOPSIS ✨

Literally this, bestie:

void workqueue_set_min_active (struct workqueue_struct *wq , int
       min_active );

---

🎀 ARGUMENTS 🎀

• wq — target unbound workqueue. She's the one getting her min_active adjusted. 🫶
• min_active — new min_active value. The fresh number, periodt. ✨

---

🦋 DESCRIPTION 🦋

Set min_active of an unbound workqueue. Important vibe: unlike other types of workqueues, an unbound workqueue is not guaranteed to be able to process max_active interdependent work items. Instead, an unbound workqueue is guaranteed to be able to process min_active number of interdependent work items, which is WQ_DFL_MIN_ACTIVE by default. 🌈

Use this function to adjust the min_active value between 0 and the current max_active. That's the whole assignment, bestie — range-coded, not extra. 💖
