sata_async_notification(9)

💖 NAME 💖

Welcome to the Kernel API Manual, bestie — this is sata_async_notification(9), the SATA async notification handler. It’s giving “I handle the notification vibe” and honestly? Iconic. ✨

🎀 SYNOPSIS 🎀

int sata_async_notification (struct ata_port *ap );

🌸 ARGUMENTS 🌸

• ap — the ATA port where async notification is received. That’s the whole argument, bestie. 🫶

🦋 DESCRIPTION 🦋

So like, this is the handler to be called when async notification via SDB FIS is received. It schedules EH if necessary — literally only when it’s necessary, no extra drama. 💅

LOCKING: spin_lock_irqsave(host lock) — bestie, this is the lock situation and you need to respect it. Do not come for this function without that host lock handled via spin_lock_irqsave. Periodt. 🔥

🌈 RETURN 🌈

Returns 1 if EH is scheduled, 0 otherwise. Clean. Simple. Ate. 💖
