💖 libnvme(9) — the API Manual, bestie edition 💖

omg hi. so this page lives in the libnvme API Manual (yes, section 9, we love a kernel-adjacent moment), and it's all about one little enum called enum nvme_st_valid_diag_info. it's giving "valid diagnostic information" and honestly? iconic. let's get into it 🫶

✨ NAME ✨

enum nvme_st_valid_diag_info — Valid Diagnostic Information

like literally the whole point is which fields in the diagnostic info actually mean something. slay.

---

🌸 SYNOPSIS 🌸

enum nvme_st_valid_diag_info {
    NVME_ST_VALID_DIAG_INFO_NSID ,
    NVME_ST_VALID_DIAG_INFO_FLBA ,
    NVME_ST_VALID_DIAG_INFO_SCT ,
    NVME_ST_VALID_DIAG_INFO_SC

};

no cap, that's the whole thing. four constants, zero drama 💅

👑 Constants 👑

okay so every one of these is a "if set, then the contents of X field are valid" situation. it's a vibe check for individual fields, and each one passes or fails on its own 🎀

• NVME_ST_VALID_DIAG_INFO_NSID — NSID Valid: if this bad boy is set, then the contents of the Namespace Identifier field are valid. that's it, that's the whole job ✨
• NVME_ST_VALID_DIAG_INFO_FLBA — FLBA Valid: if set, then the contents of the Failing LBA field are valid. yes bestie, Failing LBA, the name is doing the most but it's accurate 💀
• NVME_ST_VALID_DIAG_INFO_SCT — SCT Valid: if set, then the contents of the Status Code Type field are valid. three letters, one very important job 🔥
• NVME_ST_VALID_DIAG_INFO_SC — SC Valid: if set, then the contents of the Status Code field are valid. and that's the last one, we ate 🌈

lowkey the whole pattern here is: each flag only vouches for its own field. so if a flag isn't set, don't go reading that field like it's gospel, okay? 🙈
