ata_eh_autopsy(9)

💖 NAME 💖

okay so this is the Kernel API Manual entry for ata_eh_autopsy(9), and the official one-liner is: analyze error and determine recovery action. It’s literally the “what happened, bestie?” pass for ATA error handling — not me being dramatic, that’s the job.

✨ SYNOPSIS ✨

the signature is giving:

void ata_eh_autopsy (struct ata_port *ap );

No return value to catch — it’s void, periodt.

🫶 ARGUMENTS 🫶

• ap — the host port to perform autopsy on. yes, the patient is a host port, and we’re doing a whole diagnostic moment on it. 💅

🔍 DESCRIPTION 🔍

This bad boy analyzes all links of ap and determines why they failed and which recovery actions are needed. That’s the whole plot: inspect the links, find the failure tea, and decide what recovery moves are required. iconic diagnostic behavior, no cap.

🔒 LOCKING 🔒

LOCKING: Kernel thread context (may sleep).

💤 so yes bestie, it may sleep — that’s the locking note, keep it close.
