🌸 NAME 🌸

liveupdate_reboot — Kernel reboot notifier for live update final serialization.

---

🎀 SYNOPSIS 🎀

int liveupdate_reboot (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. literally none, bestie, it takes nothing 💅

---

💜 DESCRIPTION 💜

This function is invoked directly from the reboot syscall pathway if kexec is in progress. 👀

If any callback fails, this function aborts KHO, undoes the freeze callbacks, and returns an error. no cap, that's the whole vibe check 😭

bestie note: the failure behavior is the important part — it aborts KHO, undoes the freeze callbacks, and returns an error. keep that in mind 🫶
