can_parent_afford_sla(9)

✨ can_parent_afford_sla(9) — the "can ur parent actually afford this" check 🎀

okay bestie, so this one lives in the Kernel API Manual (section 9, kernel developer vibes 💅) and it's literally the bouncer at the club door for SLA creation. Let's get into it 🦋

---

🌸 NAME 🌸

can_parent_afford_sla — verifies if parent allows to create an SLA ✨

---

🫶 SYNOPSIS 🫶

bool can_parent_afford_sla (struct adf_rl_sla_input_data *sla_in ,
struct rl_sla *sla_parent , u32 sla_cir , bool is_update );

---

💖 ARGUMENTS 💖

• sla_in — pointer to user input data for a new SLA
• sla_parent — pointer to parent SLA object
• sla_cir — current child CIR value (only for update)
• is_update — request is a update

---

👑 DESCRIPTION 👑

So the algorithm verifies if parent has enough remaining budget to take assignment of a child with provided parameters. Like, does the parent's wallet stretch that far? 💸

In update case current CIR value must be returned to budget first — gotta put the old money back before you spend the new money, iykyk.

And no cap: PIR value cannot exceed the PIR assigned to parent. That's a hard limit, bestie. 🚫

---

🔥 RETURN 🔥

• true — SLA can be created ✅ slay
• false — SLA cannot be created 💀
