STRUCT SLOT_COUNT_REQ(9)

💜 struct slot_count_req(9) 💜

okay bestie, welcome to another page of the Kernel API Manual — this one's struct slot_count_req(9) and honestly? it's giving minimalist icon behavior. she's small. she's mysterious. she has one job. let's get into it ✨

---

🌸 NAME 🌸

struct slot_count_req — a SLOT_COUNT request. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

here's the entire struct, no cap, copy it exactly:

struct slot_count_req {
    u8 unused;
};

that's her. one whole member. she ate and left no crumbs 💅

---

🌈 Members 🌈

• unused — okay so this field exists purely to dodge weird sizeof edge cases. like, it's not used for anything, it's structural support, it's the scaffolding of the struct world 🫶 ngl it's kind of iconic that the whole member is literally just there so the size math doesn't get freaky on you.

lowkey a reminder that in kernel-land, even an empty-ish struct is a whole mood and sizeof will absolutely make it your problem if you don't give it something to chew on 😭
