libnvme(2)

✨ NAME ✨

okay bestie, so this is libnvme section 2 — the API manual, and today's main character is literally:

struct nvme_zns_changed_zone_log — the ZNS Changed Zone List log 🦋

that's it. that's the whole vibe. it's a struct, it's giving ZNS, it's logging changed zones, and we're gonna stan every last byte of it 💅

---

📦 SYNOPSIS 📦

here's the whole thing, verbatim, no crumbs left behind:

struct nvme_zns_changed_zone_log {
    __le16 nrzid;
    __u8 rsvd2[6];
    __le64 zid[NVME_ZNS_CHANGED_ZONES_MAX];
};

that's the layout, periodt. three members, one struct, zero drama ✨

🎀 Members 🎀

okay so let's go through them one by one, no skipping, i would never 🙈

• nrzid — the Number of Zone Identifiers. it's a __le16, so little-endian, so don't be out here reading it raw on a big-endian machine bestie, that's a whole different story. this lil guy tells you how many zone IDs you actually got 💖
• rsvd2 — Reserved. it's __u8 rsvd2[6], so six whole bytes of nothing, just space being held for the future like a seat reservation at a concert. do not touch it. do not read meaning into it. it's reserved, it's resting, let it rest 😌
• zid — the Zone Identifier. specifically it's __le64 zid[NVME_ZNS_CHANGED_ZONES_MAX] — an array, so it's giving many zone IDs, up to NVME_ZNS_CHANGED_ZONES_MAX of them, each one a little-endian 64-bit number. absolute queen behavior 👑

lowkey important: those are little-endian types (__le16, __le64), so byte order is not vibes-based, it's real. and zid is capped by NVME_ZNS_CHANGED_ZONES_MAX — that's the ceiling, no cap 🧢

🌈 SEE ALSO 🌈

hmm, so... this page doesn't actually list any SEE ALSO references. there's nothing after the Members section except the footer. no extra man pages, no cross-refs, no "go read this next." we're flying solo, bestie 🦋✨

and that's a wrap on struct nvme_zns_changed_zone_log fr fr 💜 may your zones change and your logs stay little-endian.

this was the libnvme API Manual, section 2, dated July 2026 — tysm for reading, you ate that, no notes 💅✨🎀
