💅 wq_adjust_max_active(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual, section 9 (that's the kernel-functions section, iykyk). today's main character is wq_adjust_max_active, and honestly? she's a tiny little function with one job and she does it. ✨

🌸 NAME 🌸

wq_adjust_max_active — update a wq's max_active to the current setting

like literally that's it, that's her whole personality, and we respect it 🫶

🦋 SYNOPSIS 🦋

void wq_adjust_max_active (struct workqueue_struct *wq );

no return value, she just does the thing and leaves 💅

🎀 ARGUMENTS 🎀

  • wq — the target workqueue. the one being adjusted. the main character of the operation. you hand her a workqueue and she goes to work on it 🧚

⭐ DESCRIPTION ⭐

okay so here's the whole vibe check, bestie, and it's honestly just two branches — a very binary situation:

  • if wq isn't freezing → set wq->max_active to the saved_max_active, and activate inactive work items accordingly. she's back, she's thriving, the inactive items get to come out and play 🔥
  • if wq is freezing → clear wq->max_active to zero. full ice queen mode. nothing runs. 💀

so basically: freezing workqueue = max_active is 0; not freezing = max_active goes back to whatever was saved_max_active, and the inactive work items wake up accordingly. no cap. 🌈
