ata_pci_remove_one(9)

💖 ata_pci_remove_one(9) 💖

Kernel API Manual bestie check-in: we are literally reading the page for a PCI device-removal callback, and it's short, so hydrate and let's go. 💅

🌸 NAME 🌸

ata_pci_remove_one — PCI layer callback for device removal

✨ SYNOPSIS ✨

void ata_pci_remove_one (struct pci_dev *pdev );

🎀 ARGUMENTS 🎀

• pdev — PCI device that was removed

🦋 DESCRIPTION 🦋

Okay so the PCI layer is telling libata, via this hook, that a hot-unplug or module unload event has occurred. The move is: detach all ports. Resource release is handled via devres.

LOCKING: Inherited from PCI layer (may sleep).
