libnvme(2)

✨ NAME ✨

struct nvme_std_perf_attr — okay bestie, this is the Standard performance attribute structure and it's literally just a little container of vibes 🫶

---

🦋 SYNOPSIS 🦋

struct nvme_std_perf_attr {
    __u8 rsvd0[4];
    __u8 r4karl;
    __u8 rsvd5[4091];
 };

not me counting the bytes... 4 + 1 + 4091, and yeah it lands on a very tidy number 💅 iykyk

---

👑 Members 👑

• rsvd0 — Reserved 🙈 nothing to see here, it's giving placeholder energy, hands off bestie
• r4karl — Random 4 KiB average read latency ⭐ this is THE one, the main character of this struct, the whole reason we're here fr fr
• rsvd5 — Reserved 😭 also just sitting there taking up space like a true reserved icon

---

so yeah. one struct, three members, two of them are Reserved and one of them is the actual moment. periodt. 💖
