htb_add_to_wait_tree(9)

✨ NAME ✨

okay so this is htb_add_to_wait_tree, and yes bestie, it's from the Kernel API Manual — the full page name is htb_add_to_wait_tree(9). Its whole vibe is adds class to the event queue with delay 💅✨

---

🦋 SYNOPSIS 🦋

void htb_add_to_wait_tree (struct htb_sched *q , struct htb_class *cl ,
       s64 delay );

it's void, so no return-value drama, periodt 💀

---

🌸 ARGUMENTS 🌸

• q — the priority event queue 🎯
• cl — the class to add 🫶
• delay — delay in microseconds ⏳

---

🎀 DESCRIPTION 🎀

The class is added to priority event queue to indicate that class will change its mode in cl->pq_key microseconds. So basically the queue is getting a lil heads-up that this class is gonna switch up its mode in exactly cl->pq_key microseconds, iykyk 🧚✨

bestie, make sure that class is not already in the queue. fr fr, that's the rule 🙈
