🌸 lpfc_pci_remove_one_s4(9) — Kernel API Manual 🌸

okay so bestie, welcome to the Kernel API Manual page for lpfc_pci_remove_one_s4(9) — yes, that’s the whole manual name folded in near the top like a cute lil name tag. This is the SLI-4 PCI removal cleanup moment, and we’re keeping every single detail. no cap. ✨

💖 NAME 💖

lpfc_pci_remove_one_s4 — PCI func to unreg SLI-4 device from PCI subsystem.

🎀 SYNOPSIS 🎀

void lpfc_pci_remove_one_s4 (struct pci_dev *pdev );

🫶 ARGUMENTS 🫶

• pdev — pointer to PCI device. that’s the PCI device pointer, periodt. 💅

✨ DESCRIPTION ✨

This routine is called from the kernel’s PCI subsystem for a device with SLI-4 interface spec. so iconic of it.

When an Emulex HBA with SLI-4 interface spec is removed from the PCI bus, it performs all the necessary cleanup for the HBA device to be removed from the PCI subsystem properly. yes, the whole cleanup arc — main character energy fr fr. 🦋
