iommufd_access_unpin_pages(9)

🎀 NAME 🎀

Okay bestie, welcome to the Kernel API Manual page for iommufd_access_unpin_pages(9) — manual name folded in right here instead of the boring header line, slay 💅.

iommufd_access_unpin_pages — undo iommufd_access_pin_pages 🫶

---

🌸 SYNOPSIS 🌸

       void iommufd_access_unpin_pages (struct iommufd_access *access ,
       unsigned long iova , unsigned long length );

---

✨ ARGUMENTS ✨

• access — the IOAS access to act on 💜
• iova — starting IOVA ✨
• length — number of bytes to access 🍓

---

🦋 DESCRIPTION 🦋

So this one returns the struct page's — yep, page's, that's literally what the original says, and we are not editing it, no cap 😭.

Before you call this, the caller must stop accessing them. And the iova/length must exactly match the one provided to access_pages — no improvising, bestie, the vibe check is strict 💀.
