STRUCT LUO_SESSION_HEADER(9)

💖 struct luo_session_header(9) 💖

okay so bestie, grab your emotional support tea 🍓 — this is the manual page for struct luo_session_header, and it's literally the main character header struct for managing LUO sessions. it lives in the Kernel API Manual and we're gonna get through it together, no cap ✨

🌸 NAME 🌸

struct luo_session_header — the header struct for managing LUO sessions. that's it, that's the vibe 💅

---

✨ SYNOPSIS ✨

here's the whole struct, copied exactly, don't touch it:

struct luo_session_header {
    long count;
    struct list_head list;
    struct rw_semaphore rwsem;
    struct kho_block_set block_set;
    u64 *sessions_pa;
    bool active;
 };

like, look at her. six fields. iconic. 👑

🎀 Members 🎀

okay bestie, field-by-field, let's go 🫶

• count — the number of sessions currently tracked in the list. she's keeping score fr fr 🔥
• list — the head of the linked list of struct luo_session instances. this is where all the session besties hang out 🌈
• rwsem — a read-write semaphore providing synchronized access to the session list and other fields in this structure. she's the bouncer at the club, keeping everything orderly 💅
• block_set — the set of serialization blocks. that's the whole description, don't ask me for more, i only report what's on the page 🧚
• sessions_pa — points to the location of sessions_pa within struct luo_ser. yes, sessions_pa points at sessions_pa. she's a little self-referential queen, we love her 🙈
• active — set to true when first initialized. if the previous kernel did not send session data, active stays false for incoming. lowkey the most important vibe check here 👀

• Kernel file ./kernel/liveupdate/luo_session.c

go read those too bestie, i believe in you 🌟

okay actual note: this page is short but every single field matters, so don't skip the active bit — that false-for-incoming case is real 💀

sign-off time 🎀 this lil beauty comes from ./kernel/liveupdate, dated October 2026, and it's the struct luo_session_header(9) page of the Kernel API Manual. slay, go forth and manage those sessions 💜🦋
