tb_cfg_request_cancel(9)

✨ NAME ✨

okay so bestie, this is tb_cfg_request_cancel(9) from the Kernel API Manual — and its whole vibe is Cancel a control request. iconic, honestly.

🛠️ SYNOPSIS 🛠️

void tb_cfg_request_cancel (struct tb_cfg_request *req , int err );

🧾 ARGUMENTS 🧾

• req — the request to cancel. yes, that one.
• err — the error to assign to the request.

💅 DESCRIPTION 💅

This function can be used to cancel ongoing request. It will wait until the request is not active anymore.

so it’s lowkey giving patient main character energy: you ask it to cancel, and it waits for the request to stop being active before it’s done. no cap. 🫶
