💅 libnvme(9) — NAME 💅

okay so bestie, welcome to libnvme(9), the API manual that's literally about to make you an expert on one extremely specific struct ✨

struct nvme_exported_ctrl_assoc_data — the Associate Controllers Management Operation Data Buffer 🎀

like, it's the data buffer for the Associate Controllers Management operation. that's the whole vibe. no cap.

✨ SYNOPSIS ✨

struct nvme_exported_ctrl_assoc_data {
    __le16 n;
    __u8 rsvd2[2];
    struct nvme_exported_ctrl_assoc_descriptor entries[];
 };

look at her. three members. flawless. main character energy fr fr 🌸

🦋 Members 🦋

• n — the Number of Associated Exported Controller Descriptors (N), and it's 0's based 💀 so yeah, zero-based, that's just how she is, we don't question it. __le16, little-endian, iconic.
• rsvd2 — Reserved. that's it. that's the whole description. __u8 rsvd2[2], two bytes of absolutely do-not-touch 🙈 hands off, bestie, reserved means reserved.
• entries — the Exported Controller Association Descriptor list, see struct nvme_exported_ctrl_assoc_descriptor 👑 this is the flexible array member at the end, lowkey the whole point of the struct, and it's giving "the real content starts here". go read that other struct, iykyk 🫶

quick vibe check: rsvd2 is Reserved. do not write to it. do not look at it too long. do not perceive it. 💅

mwah 💖 that's the whole page. you ate that. periodt.

this has been struct nvme_exported_ctrl_assoc_data from the libnvme(9) manual, dated October 2026 — source and version: the libnvme API Manual, manual name libnvme(9) 🎀 go forth and associate those exported controllers, bestie 🎀
