STRUCT PDS_LM_STATE_SIZE_COMP(9)

💅 struct pds_lm_state_size_comp — Kernel API Manual (section 9) ✨

okay bestie, welcome to the glow-up of struct pds_...te_size_comp(9) — yes that's literally how the header truncates it, she's shy 🫶 — this is the Kernel API Manual page for the STATE_SIZE command completion. We're gonna get you fluent, no cap.

---

🌸 NAME 🌸

struct pds_lm_state_size_comp — the STATE_SIZE command completion. That's it, that's the whole vibe. 💖

---

🎀 SYNOPSIS 🎀

struct pds_lm_state_size_comp {
    u8 status;
    u8 rsvd;
    __le16 comp_index;
    union {
      __le64 size;
      u8 rsvd2[11];
    };
    u8 color;
 };

Look at her. Iconic. Structured. The union is giving main character energy ngl. 🦋

---

✨ Members ✨

okay so here's the member-by-member tea, and I'm keeping every last one:

• status — the status of the command. She's an enum pds_core_status_code, so she comes pre-labeled. 💅
• rsvd — word boundary padding. Not lore, just vibes (and alignment). 🌸
• comp_index — index in the desc ring for which this is the completion. Yeah, that ring. 👑
• {unnamed_union} — an anonymous union, living her unnamed truth. No name, all presence. 🧚
• size — size of the device state. Literally the whole point of the struct, she ate. 🔥
• rsvd2 — word boundary padding, the sequel. Same energy, still padding. 🫶
• color — the color bit. A single bit of pure aesthetic. 🌈

fr fr, the padding members are load-bearing — don't go deleting them because they "look boring". That's the word boundary, bestie. 😭
