✨ NAME ✨

okay so welcome to the libnvme(9) API Manual page for struct nvme_fdp_config_desc — aka the FDP Configuration Descriptor. That's the name, that's the vibe, and it's literally giving exactly what it says on the tin 💅✨

🦋 SYNOPSIS 🦋

bestie, here's the shape of it — and yes, every single field is staying exactly where it belongs, no cap:

struct nvme_fdp_config_desc {
    __le16 size;
    __u8 fdpa;
    __u8 vss;
    __le32 nrg;
    __le16 nruh;
    __le16 maxpids;
    __le32 nnss;
    __le64 runs;
    __le32 erutl;
    __u8 rsvd28[36];
    struct nvme_fdp_ruh_desc ruhs[];
};

💅 Members 💅

now for the member-by-member vibe check — every field, zero skips, fr fr 🫶

• size — Descriptor size. iconic little size field behavior 👑
• fdpa — FDP Attributes (enum nvme_fdp_config_fdpa). yes, the enum name stays, we don't play about it 💖
• vss — Vendor Specific Size. vendor-specific and valid ✨
• nrg — Number of Reclaim Groups. count 'em 🌸
• nruh — Number of Reclaim Unit Handles. more counting, we love to see it 🎀
• maxpids — Max Placement Identifiers. the max, literally 💀
• nnss — Number of Namespaces Supported. namespaces got support 🦋
• runs — Reclaim Unit Nominal Size. nominal size era 🌈
• erutl — Estimated Reclaim Unit Time Limit. estimated, not guessed — okay maybe estimated 😭
• rsvd28 — Reserved. it's reserved, bestie, leave it alone 🙈
• ruhs — Reclaim Unit Handle descriptors (struct nvme_fdp_ruh_desc). descriptors within descriptors, we love a nested moment 🧚

lowkey this whole page is just the struct and its members, and that's the point. no extra lore, no invented behavior, just the facts in a cute little group chat format 💜

that's the whole page, bestie! this was struct nvme_fdp_config_desc from libnvme(9), dated October 2026 — mwah 💋🎀
