💅 llc_sap_remove_socket(9) — a Kernel API Manual moment

okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for llc_sap_remove_socket(9) — yes the whole (9) is part of the name, that's the section number, we love a numbered section, it's giving very organized of the kernel fr fr 🎀

✨ NAME ✨

llc_sap_remove_socket — removes a socket from SAP. that's it. that's the whole job. she's a remover. an icon. 💅

---

✨ SYNOPSIS ✨

void llc_sap_remove_socket (struct llc_sap *sap , struct sock *sk );

okay so note the void — she gives you nothing back, no return value, no little treat, just vibes and a side effect. 🦋

---

✨ ARGUMENTS ✨

• sap — SAP. yes the manual literally just says "SAP" and honestly? valid. it's the struct llc_sap *, the Service Access Point, the whole point of the operation. 👑
• sk — socket. again, extremely concise of them. it's the struct sock *, the socket we're plucking out. 🫶

---

✨ DESCRIPTION ✨

so here's the tea 🍓 — this function removes a connection from the hash tables of a SAP, but ONLY if the connection was in this list. conditional queen. she's not out here removing things that aren't there, she's checking first. main character energy with a guard clause. 😭

literally that's the function. hash table cleanup. no cap.
