ib_unregister_mad_agent(9)

💖 ib_unregister_mad_agent 💖

okay so this is a Kernel API Manual page, and it's lowkey the “log out of MAD services” button for a client 💅. The function is ib_unregister_mad_agent, and the vibe is very “cleanup era, no cap.”

---

🎀 NAME 🎀

ib_unregister_mad_agent — unregisters a client from using MAD services. Periodt. 💫

---

✨ SYNOPSIS ✨

void ib_unregister_mad_agent (struct ib_mad_agent *mad_agent );

---

🌸 ARGUMENTS 🌸

• mad_agent — the corresponding MAD registration request you're deregistering. Like, the exact registration request you wanna un-register, bestie 🫶.

---

🦋 DESCRIPTION 🦋

After invoking this routine, MAD services are no longer usable by the client on the associated QP. That's the whole tea 😭 — unregister goes through, and the client's MAD-services era on that associated QP is over.

So yeah: once this routine is invoked, don't expect MAD services to still be usable by that client on the associated QP, fr fr 💀.
