💖 libnvme(9) 💖

okay so bestie, welcome to the API Manual — yes that's the manual name, we're fancy here — and today's main character is a struct. literally a struct. don't scroll away, it's cute, I promise 🫶

---

✨ NAME ✨

struct nvme_zone_report — the Report Zones Data Structure. that's it, that's the whole vibe check. it's giving "I hold zone descriptors and I'm not sorry" 🌸

---

✨ SYNOPSIS ✨

here's the whole thing, no cap, exactly as it lives:

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

look at her. three members. one of them is literally an array with no size because she's flexible like that 💅

---

✨ Members ✨

okay so let's go member by member, because every single one matters and I refuse to skip any of them:

• nr_zones — the Number of descriptors in entries. she's the counter, the headcount, the "how many besties are coming to the party" field. __le64, so little-endian, iykyk 🎀
• rsvd8 — Reserved. that's it. that's the whole description. it's a __u8 rsvd8[56] and it is Reserved. do not touch her, do not look at her, she is simply Reserved and living her life 💀
• entries — the Zoned namespace descriptors. this is the actual good stuff, the payload, the reason we're all here. it's a struct nvme_zns_desc flexible array member — main character energy for real 🔥

bestie note: entries has no declared size in the brackets. that's not me being sloppy, that's exactly how it's written. don't come for me 🙈

🌈 that's the whole page 🌈

no hidden options, no environment variables, no exit statuses, no SEE ALSO — this struct keeps it minimal and honestly? iconic. obsessed. periodt 💜

sign-off time, because the footer deserves love too: this little page comes from libnvme(9), the struct nvme_zone_report entry in the API Manual, and it's dated October 2026 — so bookmark it, screenshot it, send it to the group chat, whatever you need 🧚💖⭐
