libnvme(2)

✨ NAME ✨

okay so bestie, gather round 💖 this is libnvme(2) — the API manual page for struct nvme_zone_report, aka the Report Zones Data Structure. it's giving "the receipt for all your zoned namespace zones" and honestly? iconic. 👑

---

🌸 SYNOPSIS 🌸

here's the whole vibe, verbatim, do NOT touch a single character bestie:

struct nvme_zone_report {
    __le64 nr_zones;
    __u8 rsvd8[56];
    struct nvme_zns_desc    entries[];
 };

that's it. that's the struct. she's simple, she's sleek, she's serving. 💅

• nr_zones — the number of descriptors chillin' inside entries. that's the count, the headcount, the "how many of y'all are in here" number. it's an __le64, so little-endian, no cap. ✨
• rsvd8 — reserved. literally just __u8 rsvd8[56]; — 56 bytes of "please don't touch, this space is reserved", the padding that's minding its own business. 🙈 do not poke it, she said what she said. 💀
• entries — the zoned namespace descriptors themselves 🎀 an array of struct nvme_zns_desc, and yes it's flexible-array style with the empty brackets, so it's however long nr_zones says it is. main character energy fr fr, she grows to fit the moment. 🌈

ngl bestie, that's a lot of reserved bytes and we respect the boundaries. 🫶

and that's the whole page!! slay 💖 this little gem comes from the libnvme API Manual, dated July 2026, and it's all about struct nvme_zone_report in the good ol' libnvme(2). go forth and report your zones, queen 👑✨ 🦋🌸💜
