💖 NAME 💖

okay bestie, welcome to libnvme(9) — we're looking at one very specific little struct, and it's giving low-level NVMe energy:

struct nvme_host_addressable_ns_data — Addressable Namespaces Data Structure

✨ SYNOPSIS ✨

Here's the whole struct, no cap — every field stays exactly as written:

       struct nvme_host_addressable_ns_data {
           __le32 nsid;
           __u8 mat;
           __u8 rsvd5[3];
           __le64 memo;
        };

🌸 Members 🌸

• nsid — Namespace Identifier, and bestie, it may or may not be attached to the controller processing the command. That's the whole vibe.
• mat — Memory Access Type, see enum nvme_host_addressable_ns_mat.
• rsvd5 — Reserved. Yes, reserved means reserved — hands off, bestie 💅
• memo — Memory Offset: the offset of the memory address for this namespace from the base address of the memory access type indicated in mat.

okay that's the whole struct, bestie — go forth and vibe-check those namespaces 🫶
