ata_qc_complete(9)

💖 ata_qc_complete(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual page for ata_qc_complete(9) — the little function that announces an ATA command is done. We're keeping every detail, no cap. 💅

---

🌸 NAME 🌸

ata_qc_complete — complete an active ATA command ✨

🦋 SYNOPSIS 🦋

void ata_qc_complete (struct ata_queued_cmd *qc );

🎀 ARGUMENTS 🎀

• qc — the command to complete 💖

💜 DESCRIPTION 💜

This is literally the “hey bestie, it’s done” signal to the mid and upper layers that an ATA command has completed, with either an ok or not-ok status. Periodt.

⚠️ Do not call this function multiple times when you’re successfully completing multiple NCQ commands. Use ata_qc_complete_multiple instead — that one will properly update IRQ expect state. This is the rule, okay? 😭

LOCKING: spin_lock_irqsave(host lock)
