scsi_device_get(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 scsi_device_get(9) 🦋

okay bestie, welcome to the Kernel API Manual page for scsi_device_get(9) — it's giving reference-counting realness and we're gonna get through it together 🫶✨

💖 NAME 💖

scsi_device_get — get an additional reference to a scsi_device, periodt. It's the +1 bestie your device needs 💅

✨ SYNOPSIS ✨

here's the exact signature, no cap:

int scsi_device_get (struct scsi_device *sdev );

🎀 ARGUMENTS 🎀

  • sdev — the device you're getting a reference to. That's the whole assignment, bestie 🍓

🌸 DESCRIPTION 🌸

Okay so scsi_device_get gets a reference to the scsi_device and increments the use count of the underlying LLDD module. No cap.

⚠️ bestie, you must hold host_lock of the parent Scsi_Host, or already have a reference when calling this. Those are the rules, fr fr.

This will fail if a device is deleted or cancelled, or when the LLD module is in the process of being unloaded. So if teardown is happening, do not expect this to slay 😭
