libnvme(2)

✨ NAME ✨

okay bestie, gather round 💖 this is struct nvme_fdp_ruhu_log — the Reclaim Unit Handle Usage Log Page. yes it's a whole mouthful, no you don't have to say it out loud. it lives in libnvme(2), the API manual, and it's giving very much "NVMe FDP bookkeeping" energy 🦋

---

🌸 SYNOPSIS 🌸

struct nvme_fdp_ruhu_log {
    __le16 nruh;
    __u8 rsvd2[6];
    struct nvme_fdp_ruhu_desc ruhus[];
 };

look at her. so compact. so structured. the way she just... declares herself like that 😭 iconic honestly.

🎀 Members 🎀

• nruh — Number of Reclaim Unit Handles. that's the count, bestie. it's a __le16, so little-endian, and it's literally telling you how many reclaim unit handles you're working with 🔥
• rsvd2 — Reserved. it's a __u8 rsvd2[6] sized gap, which is the struct's polite way of saying "nothing to see here, move along, don't touch, don't write, this space is booked 🙈". reserved means reserved, fr fr.
• ruhus — Reclaim Unit Handle Usage descriptors. a flexible array of struct nvme_fdp_ruhu_desc sitting at the end of the struct 🫶 it just... keeps going. however many need to be there, that's how many there are. main character energy tbh 👑

ngl, the trailing [] array means the size of this struct is not fixed — it's whatever the header plus however many descriptors follow. do not assume, bestie. 💅
