✨ NAME ✨

struct nvme_media_unit_stat_log — Media Unit Status 💾✨

okay so bestie, this is a struct from libnvme(2), aka the API Manual, and it's basically the receipts for your media unit status. let's get into it 🫶

---

🌸 SYNOPSIS 🌸

the way this thing is shaped, fr fr:

struct nvme_media_unit_stat_log {
    __le16 nmu;
    __le16 cchans;
    __le16 sel_config;
    __u8 rsvd6[10];
    struct nvme_media_unit_stat_desc mus_desc[];
 };

like. look at her. an icon honestly 👑

🎀 Members 🎀

• nmu — Number unit status descriptor. yep, that's the number of unit status descriptors and she said it in the most literal way possible 💅
• cchans — Number of Channels. it's giving "how many channels do we have" and the answer is this many 🌈
• sel_config — Selected Configuration. the one config that got picked, main character energy fr 💖
• rsvd6 — Reserved. do NOT touch her. she is reserved for a reason, this is your reminder to leave that field alone 🙈
• mus_desc — Media unit statistic descriptors. the actual stats, the whole point, the moment we've all been waiting for ✨

---

lowkey important: nmu tells you how many descriptors to actually look at, and mus_desc is a flexible array member (that empty [] is not a typo bestie, that's the vibe). the reserved rsvd6[10] stays reserved. no cap. 💀

that's the whole struct. she's small but she's doing a lot 🦋
