libnvme(9)

📦 version 3.2, in arch rolling

💖 libnvme(9) — the API Manual, bestie 💖

Okay so this page lives in the libnvme man pages (that's the manual name, iykyk), and it's all about one little struct. Let's get into it ✨

🌸 NAME 🌸

struct nvme_registrant_ext — the Registrant Extended Data Structure. That's her full legal name, no nicknames 💅

🦋 SYNOPSIS 🦋

Here's the whole glow-up, exactly as it is, no edits from me:

struct nvme_registrant_ext {
    __le16 cntlid;
    __u8 rcsts;
    __u8 rsvd3[5];
    __le64 rkey;
    __u8 hostid[16];
    __u8 rsvd32[32];
 };

🎀 Members 🎀

Time for the member-by-member vibe check, one at a time, no skipping 👑

  • cntlid — the Controller ID 🫶
  • rcsts — the Reservation Status ✨
  • rsvd3 — Reserved (aka not her moment, hands off) 🙈
  • rkey — the Reservation Key 🔑
  • hostid — the Host Identifier 💖
  • rsvd32 — Reserved (again — respect the reserved fields, bestie) 💀

And that's the whole page, fr fr — every field accounted for, nothing dropped, nothing invented 🧚

Little reminder that rsvd3 and rsvd32 are reserved, so don't go poking at them like they're main character fields 💅

Sign-off time, bestie: this was brought to you by the API Manual for libnvme(9), dated October 2026 — literally iconic, obsessed, periodt 🌈⭐👑
