launch_data_...io_ack_queue(9)

Hey bestie 💕 welcome to the Kernel API Manual, section 9 — this is the launch_data_...io_ack_queue(9) page, and we’re gonna make it make sense. No cap, it’s a tiny one. 🎀

🫶 NAME 🫶

launch_data_vio_on_bio_ack_queue — when the vdo is using a bio_ack queue, this sets a callback to run on that queue and invokes it immediately; otherwise, it just runs the callback on the current thread. Lowkey simple, highkey important. ✨

✨ SYNOPSIS ✨

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

💅 ARGUMENTS 💅

• data_vio — -- undescribed -- (the page literally gives us -- undescribed --, so that’s all the tea we have 🍵)
• callback — -- undescribed -- (same story: -- undescribed --; no extra lore, bestie 🙈)
