💖 arch_crash_...otplug_event(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is short, sweet, and honestly kind of iconic. no cap, it's giving "tiny function, big hotplug energy." ✨

---

✨ NAME ✨

arch_crash_handle_hotplug_event — Handle hotplug elfcorehdr changes 🫶

---

🦋 SYNOPSIS 🦋

void arch_crash_handle_hotplug_event (struct kimage *image , void *arg
);

it returns void, so like… no return value to stan, just vibes 💅

---

🎀 ARGUMENTS 🎀

• image — a pointer to kexec_crash_image. that's the main character right there 👑
• arg — a struct memory_notify handler for the memory hotplug case, and NULL for the CPU hotplug case. so bestie, it's either a whole notify struct or literally NULL, no in-between 😭

---

💅 DESCRIPTION 💅

Prepare the new elfcorehdr and replace the existing elfcorehdr. that's it, that's the whole assignment — prep the new one, swap out the old one, periodt 🔥

ngl this is the entire description, so don't go looking for extra lore. it's short, it's clear, it ate. 💀
