module_dwarf_cleanup(9)

🌸 NAME 🌸

module_dwarf_cleanup — remove FDE/CIEs associated with @mod.

okay so this is the module_dwarf_cleanup(9) page from the Kernel API Manual, and it’s basically the goodbye-cleanup era for DWARF stuff when a module unloads. bestie, it’s giving “pack your bags, we’re removing your FDEs and CIEs from the global lists” energy 💅✨

---

✨ SYNOPSIS ✨

the whole signature is literally:

void module_dwarf_cleanup (struct module *mod );

return type: void — no return-value gossip here, she just does the cleanup and exits 🫶

---

🫶 ARGUMENTS 🫶

• mod — the module that is being unloaded. that’s the one whose DWARF leftovers we’re cleaning up, no cap.

---

💅 DESCRIPTION 💅

here’s the tea: module_dwarf_cleanup removes any FDEs and CIEs from the global lists that came from mod’s .eh_frame section, because mod is being unloaded. periodt. 🔥

so yeah, the module is leaving the chat, and this function yanks the FDE/CIE entries that came from its .eh_frame section out of the global lists. it’s not main character energy — it’s cleanup main character energy. iconic behavior, honestly. 🧚💖
