i91u_unmap_scb(9)

okay bestie, welcome to i91u_unmap_scb(9) from the Kernel API Manual — this is the unmap a command page, and it’s giving cleanup era 💅✨

💖 NAME 💖

i91u_unmap_scb — Unmap a command. That’s the whole assignment, fr fr 🎀

✨ SYNOPSIS ✨

void i91u_unmap_scb (struct pci_dev *pci_dev , struct scsi_cmnd *cmnd );

It’s void, so there’s literally no return value to obsess over — just unmapping business 🫶

🦋 ARGUMENTS 🦋

• pci_dev — the PCI device the command is for, iykyk 🧚
• cmnd — the command itself, the main character of this little cleanup scene 👑

🌸 DESCRIPTION 🌸

Unmap any PCI mapping/IOMMU resources that got allocated when the command was originally mapped as part of initio_build_scb. That’s it, that’s the vibe: resources that got mapped earlier are now getting unmapped. No cap 😭💖
