ata_scsi_offline_dev(9)

💅 ata_scsi_offline_dev(9) 💅

okay bestie, this page is from the Kernel API Manual, and we're talking about ata_scsi_offline_dev. no cap, it's a tiny function with a very specific job. ✨

---

🌸 NAME 🌸

ata_scsi_offline_dev — offline attached SCSI device

✨ SYNOPSIS ✨

bool ata_scsi_offline_dev (struct ata_device *dev );

🎀 ARGUMENTS 🎀

• dev — the ATA device you're doing the offline thing for: specifically, the ATA device to offline the attached SCSI device for. 🫶

🧚 DESCRIPTION 🧚

so this function gets called from ata_eh_detach_dev, and her whole main-character job is taking the SCSI device attached to dev offline. that's it, that's the task. 💅

she is called with the host lock held, and that host lock is the thing protecting dev->sdev against clearing. iykyk. 🔒

LOCKING: spin_lock_irqsave(host lock)

🔥 RETURN 🔥

• true — if the attached SCSI device exists
• false</false> — otherwise
