auth_domain_cleanup(9)

💅 auth_domain_cleanup — a Kernel API Manual moment

okay bestie, buckle up, we're in the Kernel API Manual today and the star of the show is auth_domain_cleanup(9). yes it's a function. yes it's a vibe check for your table. no it does not take arguments. let's get into it 🎀

---

✨ NAME ✨

auth_domain_cleanup — the little function that checks whether the auth_domain table is empty. that's it. that's the job. it's giving "final walkthrough before we lock up the house" 🏠✨

---

🌸 SYNOPSIS 🌸

void auth_domain_cleanup (void );

literally one line, zero drama, no params to pass. iconic behavior honestly 💅

---

🦋 ARGUMENTS 🦋

• void — no arguments. none. zero. the function said "i need nothing from you" and honestly? respect 🫶

---

💖 DESCRIPTION 💖

okay so here's the situation. on module unload, the auth_domain_table must be empty. that's the rule, that's the law, no cap. 🔥

and because catching bugs where domains don't get cleaned up properly is a whole thing, this function warns if anything remains in the table at cleanup time. so if you forgot to tidy up, you're gonna hear about it 😭 it's literally the friend who goes "bestie… you left something in the table" before you walk out the door.

🚨 important caveat, please read this part: we cannot proactively remove the domains at this stage. why? because the ->release function might be in a module that has already been unloaded. so yeah — we warn, we do NOT touch. that would be a whole mess and we are not doing that 💀
