STRUCT LUO_SESSION_SER(9)

💅 struct luo_session_ser(9) — the Kernel API Manual glow-up ✨

okay bestie, welcome to the Kernel API Manual page for struct luo_session_ser — yes it's a struct, no it's not scary, and yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

struct luo_session_ser — literally the serialized metadata for a LUO session, all packaged up and ready to travel. it's giving "my whole personality in one struct" energy 💅

---

✨ SYNOPSIS ✨

here's the whole thing, no cap, exactly as it lives in the source:

struct luo_session_ser {
    char name[LIVEUPDATE_SESSION_NAME_LENGTH];
    struct luo_file_set_ser file_set_ser;
 };

two members, that's it, she's lowkey minimalist 👑

---

🎀 Members 🎀

• name — the unique name of the session. where does it come from? userspace, babes — it's handed over at the time of session creation. so if it's weird, that's on them 😭
• file_set_ser — the serialized files that belong to this session. yes, the whole file set, packed up. it's giving "bringing my entire closet to a sleepover" 🧳✨

---

🦋 Description 🦋

so what's the ~vibe~ of this struct? it's the thing that packages up session-specific metadata so it can be transferred between kernels via Kexec Handover. iconic behavior honestly.

here's the tea: an array of these structures gets created — one per session — and passed to the new kernel, which then uses them to reconstruct the session context. so it's like handing your bestie a little note with everything she needs to keep the party going 🎉👯‍♀️

⚠️ important, don't skip this one: if this structure is modified, LUO_ABI_COMPATIBLE must be updated. no like actually. don't be the girl who forgets, we are not doing that today 💀
