launch_data...one_callback(9)

💅 launch_data...one_callback(9) — like, the Kernel API Manual, but make it cute ✨

Okay bestie, so this is a page out of the Kernel API Manual (launch_data...one_callback(9), iykyk) and it's short, but it's doing a lot. Buckle up 🎀

---

🌸 NAME 🌸

launch_data_vio_allocated_zone_callback — sets a callback as a physical block operation in a data_vio's allocated zone, then queues the data_vio and invokes it immediately. Like, no waiting around, she goes 💅

---

✨ SYNOPSIS ✨

void launch_data_vio_allocated_zone_callback (struct data_vio *data_vio
, vdo_action_fn callback );

That's the whole signature, no cap. Two args, void return, she's not giving you anything back 🫶

---

🦋 ARGUMENTS 🦋

• data_vio — -- undescribed -- 😭 the manpage literally will not tell us. Not me gatekeeping, that's just what it says.
• callback — -- undescribed -- 🙈 same vibe. The page leaves these two as total mystery main characters.

Lowkey iconic that a manual page can just ✨decline to elaborate✨ on both of its own arguments, but here we are. The facts are the facts, bestie 💀
