htb_activate_prios(9)

💖 htb_activate_prios(9) 💖 — straight from the Kernel API Manual

🌸 NAME 🌸

htb_activate_prios — creates active classe's feed chain ✨

✨ SYNOPSIS ✨

void htb_activate_prios (struct htb_sched *q , struct htb_class *cl );

🎀 ARGUMENTS 🎀

• q — the priority event queue. The queue where priority events hang out.
• cl — the class to activate. The main-character class getting switched on.

🌈 DESCRIPTION 🌈

Okay so picture this: the class is connected to ancestors and/or appropriate rows for priorities it is participating on. That's the feed-chain link-up vibe, and it's lowkey iconic.

cl->cmode must be new (activated) mode. No exceptions, bestie — if it's not in new (activated) mode, this is not the function for that.

It does nothing if cl->prio_activity == 0. Literally nothing. Zero activity, zero action, periodt. 💅
