STRUCT RL_SLA(9)

💅 struct rl_sla(9) — like, the SLA object data structure bestie

okay so this is a page from the Kernel API Manual, and it's literally about struct rl_sla — the SLA object data structure. that's it, that's the vibe. it lives deep in the kernel and it's lowkey iconic 🎀

---

✨ NAME ✨

struct rl_sla — the SLA object data structure, no cap 💖

---

🌸 SYNOPSIS 🌸

struct rl_sla {
    struct rl_sla *parent;
    enum rl_node_type type;
    enum adf_base_services srv;
    u32 sla_id;
    u32 node_id;
    u32 cir;
    u32 pir;
    u32 rem_cir;
    u16 ring_pairs_ids[RL_RP_CNT_PER_LEAF_MAX];
    u16 ring_pairs_cnt;
 };

like, there it is. the whole struct. eat it up 🔥

💅 Members 💅

so bestie, every single field has a job and here's the tea on each one:

• parent — pointer to the parent SLA (root/cluster). your fave's fave, iykyk ✨
• type — the SLA type. which flavor of SLA are we dealing with 🦋
• srv — the service associated with this SLA. it's giving "who do you belong to" 💖
• sla_id — ID of the SLA. this one's doing double duty fr fr: it's used as the element number in the SLA array and as an identifier shared with the user 👑
• node_id — ID of the node. heads up: each of the SLA types has a separate ID list ⭐
• cir — committed information rate 🌸
• pir — peak information rate, and yes, PIR >= CIR. it's a whole rule, respect it 💀
• rem_cir — okay so if this SLA is a parent, then this field represents a remaining value to be used by child SLAs. handing down the leftovers like a good parent 🫶
• ring_pairs_ids — array with the numeric ring pairs IDs assigned to this SLA. it's an array, it's full of IDs, it's doing the most ✨
• ring_pairs_cnt — the number of assigned ring pairs listed in the array above. yes, the count for the array two lines up. keeping it accountable 💅
