ata_eh_about_to_do(9)

💅 ata_eh_about_to_do(9)

Okay so bestie, welcome to the Kernel API Manual — this one's a tiny little function from the ATA error-handling corner of the kernel, and it's way less scary than the name makes it sound. Let's get into it ✨

---

🌸 NAME 🌸

ata_eh_about_to_do — literally "about to perform eh_action", the pre-game hype speech before the actual EH work happens 🎬

---

✨ SYNOPSIS ✨

void ata_eh_about_to_do (struct ata_link *link , struct ata_device *dev
, unsigned int action );

---

🎀 ARGUMENTS 🎀

• link — the target ATA link, i.e. the link we're doing the thing on 🫶
• dev — the target ATA dev for the per-dev action. Heads up: this one can be NULL 💀
• action — the action that's about to be performed, the main character of this whole function 👑

---

🦋 DESCRIPTION 🦋

So here's the vibe: this gets called just before performing EH actions, and its whole job is to clear the related bits in link->eh_info so that eh actions don't get unnecessarily repeated. That's it. That's the function. Lowkey iconic for how much chaos it prevents 🙈

It's literally the "okay we're doing this now, stop asking" of the ATA error handler. No cap.

🔒 LOCKING 🔒

None. Zero. Nada. No locks here, bestie — go forth 🧚

Fr fr, the manpage says LOCKING: None. and we are not adding anything to that. Take it at face value 💅

💖 That's the whole page, bestie! 💖

This little masterpiece lives in ./drivers/ata, and it's dated October 2026 — so yeah, it's giving future icon energy 👑 Go clear those eh_info bits and slay, periodt. 💅✨
