scsi_kunmap_atomic_sg(9)

💅 scsi_kunmap_atomic_sg(9) — from the Kernel API Manual, bestie 💖

Okay so picture this: you're in kernel land, you've got a virtual address that was mapped atomically by scsi_kmap_atomic_sg, and now it's time to let it go. That's the whole gig. This page is the "cleanup era" of atomic mapping — short, sweet, and honestly iconic.

✨ NAME ✨

scsi_kunmap_atomic_sg — atomically unmap a virtual address that was previously mapped with scsi_kmap_atomic_sg. It's giving "you brought it in, you take it out" energy 🫶

---

🌸 SYNOPSIS 🌸

void scsi_kunmap_atomic_sg (void *virt );

No return value, no drama. It returns void — literally nothing comes back, which is honestly so chill of it.

---

🎀 ARGUMENTS 🎀

• virt — the virtual address that needs to be unmapped. That's it. That's the whole argument. Hand it over and it's done 💅
