vdo_submit_data_vio(9)

🌸 NAME 🌸

Bestie, welcome to vdo_submit_data_vio(9) from the Kernel API Manual — the page where we submit I/O for a data_vio. 💅

✨ SYNOPSIS ✨

The whole signature vibe is:

void vdo_submit_data_vio (struct data_vio *data_vio );

🎀 ARGUMENTS 🎀

• data_vio — the data_vio for which to issue I/O. That's the one you're handing over, no cap. 🫶

🦋 DESCRIPTION 🦋

Okay so here's the tea: if possible, this I/O gets merged with other pending I/Os. If it can't merge, then the data_vio is sent directly to the appropriate bio zone. Lowkey simple, highkey iconic. ✨
