💖 libnvme — bestie's guide to struct nvme_lba_status 💖

okay so you're reading the libnvme manual, page 2, "API Manual" era, and today's main character is this little struct right here. it's giving LBA Status Descriptor List energy, and honestly? iconic. 🦋

---

✨ NAME ✨

struct nvme_lba_status — the LBA Status Descriptor List 🌸

no cap, that's the whole name. short. sweet. slays.

---

✨ SYNOPSIS ✨

struct nvme_lba_status {
    __le32 nlsd;
    __u8 cmpc;
    __u8 rsvd5[3];
    struct nvme_lba_status_desc descs[];
};

bestie look at it. it's a header, then some fields, then a lil flexible array doing its thing at the end. so demure. so mindful. 💅

💫 Members 💫

• nlsd — Number of LBA Status Descriptors ✨ it's a __le32, so little-endian, and it literally tells you how many descriptors you got. the count. the receipts. 🔥
• cmpc — Completion Condition 💖 a single __u8 doing the most, telling you how this thing wrapped up.
• rsvd5 — Reserved 🙈 it's __u8 rsvd5[3], which is 3 whole bytes of "don't touch, not for you, mind your business." reserved means reserved, bestie.
• descs — LBA status descriptor Entry 👑 it's declared as struct nvme_lba_status_desc descs[]; — a flexible array member, meaning the actual entries live right there after the struct. the entries are the moment fr fr.

---

⭐ quick vibe check: rsvd5 is Reserved — that's not me being dramatic, that's the spec. do not write to it. do not read meaning into it. leave the reserved bytes alone, they're just vibing. 🌈

🎀 that's the whole page 🎀

and that's it, that's the struct. you know it, you love it, you're obsessed.
