atapi_pio_bytes(9)

Welcome to atapi_pio_bytes(9) from the Kernel API Manual, bestie 💖 this one is short but it's giving “small function, big libata energy.”

💖 NAME 💖

atapi_pio_bytes — Transfer data from/to the ATAPI device.

✨ SYNOPSIS ✨

void atapi_pio_bytes (struct ata_queued_cmd *qc );

🎀 ARGUMENTS 🎀

• qc — Command on going. That's the command currently in progress, iykyk 🫶

🦋 DESCRIPTION 🦋

It does the literal thing: Transfer Transfer data from/to the ATAPI device. Yes, the page says “Transfer” twice — iconic typo behavior, we respect it 💅

LOCKING: Inherited from caller. No solo lock arc here; you're borrowing the caller's locking situation, periodt.
