💅 libnvme(9) — API Manual 💅

okay bestie, buckle up, because today we're looking at one specific little struct from the libnvme API Manual and honestly? she's giving "spreadsheet but make it NVMe" 📋✨

🌸 NAME 🌸

struct nvme_id_ns_granularity_list — Namespace Granularity List

like, literally the struct that holds the list. that's her. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

struct nvme_id_ns_granularity_list {
    __le32 attributes;
    __u8 num_descriptors;
    __u8 rsvd5[27];
    struct nvme_id_ns_granularity_desc entry[NVME_ID_ND_DESCRIPTOR_MAX];
    __u8 rsvd1056[3040];
 };

no cap, that's the entire shape of her. look at those reserved arrays just... reserving. iconic behavior honestly 🫶

💖 Members 💖

  • attributes — Namespace Granularity Attributes. the attributes field, out here holding the granularity attributes for the namespace. main character energy ⭐
  • num_descriptors — Number of Descriptors. literally tells you how many descriptors there are. she said "count them" and then gave you the count 🔢💅
  • rsvd5 — reserved. not for you, bestie. hands off 🙈
  • entry — Namespace Granularity Descriptor. this is an array of struct nvme_id_ns_granularity_desc, sized NVME_ID_ND_DESCRIPTOR_MAX — that's where the actual descriptor entries live 👑
  • rsvd1056 — reserved. again. reserved. leave her alone 😭
quick vibe check: attributes is __le32 (little-endian, iykyk), num_descriptors is a single __u8, rsvd5 is __u8 rsvd5[27], and rsvd1056 is a big ol' __u8 rsvd1056[3040]. fr fr, those numbers are exact — don't go editing them 💀

and that's the whole page, bestie 🌈 nothing skipped, nothing invented, every field accounted for like a responsible queen 👑

kisses, this was the libnvme(9) page from the API Manual, dated October 2026 — struct nvme_id_ns_granularity_list and friends, signing off 💜🦋
