ib_unregister_client(9)

💅 ib_unregister_client — like, the Kernel API Manual one, bestie

okay so real quick, the manual we're living in rn is the Kernel API Manual, and this page is ib_unregister_client(9). it's a glow-up for your cleanup era. let's go 🦋

---

✨ NAME ✨

ib_unregister_client — unregister an IB client. that's it. that's the whole vibe. you registered, now you're un-registering. character development 💖

---

🌸 SYNOPSIS 🌸

void ib_unregister_client (struct ib_client *client );

no return value, no drama, just void. she gives nothing and that's iconic 💅

---

🎀 ARGUMENTS 🎀

• client — the client you're unregistering. yes, that one. your client. the client. be normal about it 🫶

---

👑 DESCRIPTION 👑

okay so listen. upper level users use ib_unregister_client to remove their client registration. that's the whole job, she's a one-trick pony and she ATE. 🔥

when ib_unregister_client is called, the client will receive a remove callback for each IB device still registered. every single one. not a vibe check, a full sweep 🧹✨

this is a full fence, bestie. once it returns, no client callbacks will be called, or are running in another thread. like, none. zero. the door is closed, the lights are off, nobody's home. do not test this. do not be cute about this. this is the whole contract and it is fr fr load-bearing 😭

and that's the page, bestie 🍓 this has been the Kernel API Manual situation, sourced from ./drivers/infiniband/core, dated October 2026, and yes the header up top said ib_unregister_client(9) and the footer said ib_unregister_client(9) too because she contains multitudes 💜 mwah, go unregister responsibly, ily ⭐
