💖 NAME 💖

struct nvme_lockdown_log — the Command and Feature Lockdown Log, bestie. that's the whole vibe. it's a struct. it logs lockdown stuff. slay.

✨ SYNOPSIS ✨

struct nvme_lockdown_log {
    __u8 cfila;
    __u8 rsvd1[2];
    __u8 lngth;
    __u8 cfil[508];
 };

okay so literally just look at it. four fields. no cap. copy it exactly, don't get creative, the compiler is NOT your friend like that 💅

🎀 Members 🎀

• cfila — this one holds the Contents of the Command and Feature Identifier List field in the log page. it's giving "the actual goods". it's a __u8, so one byte, no notes.
• rsvd1 — Reserved. it's __u8 rsvd1[2], so two bytes of pure nothing-burger. do not touch her. do not write to her. she is simply there, minding her business, existing for the spec's sake 🦋
• lngth — the Length of Command and Feature Identifier List field. so this lil __u8 is the vibe check for how long the list actually is. if you ignore her your cfil reading is gonna be a whole mess 😭
• cfil — the Command and Feature Identifier List itself. and it's __u8 cfil[508] — five hundred and eight bytes of identifier list. that's the main character of this struct right there 👑 the way she just holds 508 bytes and doesn't complain? iconic. periodt.

heads up bestie 🔥 the size of cfil is 508 and the size of rsvd1 is 2. don't be out here swapping numbers, the struct layout is load-bearing fr fr.
