💖 libnvme(2) — API Manual 💖

okay bestie, welcome to libnvme, the API manual, and today's main character is a lil struct that's honestly kind of a big deal: struct nvme_zns_lbafe. ZNS girlies rise up 🧚✨

---

🌸 NAME 🌸

struct nvme_zns_lbafe — the LBA Format Extension Data Structure. yeah that's the whole name, she's fancy like that 💅

---

✨ SYNOPSIS ✨

struct nvme_zns_lbafe {
    __le64 zsze;
    __u8 zdes;
    __u8 rsvd9[7];
 };

no cap, that's it. three fields. she's small but she's got range 🎀

---

👑 Members 👑

not me hyping up every single field, but they all deserve it:

• zsze — Zone Size. the __le64 glow-up, little-endian and everything 🔥
• zdes — Zone Descriptor Extension Size. a single __u8, humble but essential 🫶
• rsvd9 — reserved. an array of 7 __u8s that we simply do not touch. she's reserved, literally. respect her personal space 🙈

---

lowkey a reminder for the girlies: that rsvd9 is reserved, so keep your hands off. it's giving "do not perceive me" energy 💀

---

⭐ and that's the vibe ⭐

that's the whole page, bestie. small struct, big ZNS energy. iykyk 💜
