tb_xdomain_...ding_disable(9)

💅 NAME 💅

tb_xdomain_lane_bonding_disable — bestie, this is the one that turns lane bonding off. That's it. That's the whole job. ✨

(also hi, you're reading the Kernel API Manual, section 9 — welcome to the kernel girlies club 🎀)

---

✨ SYNOPSIS ✨

void tb_xdomain_lane_bonding_disable(struct tb_xdomain *xd);

okay so just clock the return type: void. she gives nothing back. no error code, no "hey it worked", nothing. she does the thing and she leaves. main character energy honestly 💅

---

🎀 ARGUMENTS 🎀

• xd — the XDomain connection 🦋 literally just the handle to the XDomain you're trying to un-bond. that's the whole parameter list. one (1) girl.

---

🦋 DESCRIPTION 🦋

So here's the tea, bestie: lane bonding is disabled by default for XDomains. That's the default, no cap. Out of the box she's off, she's chilling, she's minding her business. 🧚

But if somebody went and enabled bonding — you know, via her sister function, we'll get to her in a sec — then you can call tb_xdomain_lane_bonding_disable to turn it off again. That's the entire plot. Enabled → not enabled. Iconic, lowkey, no notes. ✨

fr fr that's all the manpage says about behaviour, so don't come for me asking for more lore 🙈
