restore_vm_bo_list(9)

💅 restore_vm_bo_list(9) 💅

okay bestie, you've landed on restore_vm_bo_list — a page from the Kernel API Manual, and honestly it's giving "small function, big comeback energy" 🎀 let's get into it.

---

✨ NAME ✨

restore_vm_bo_list — the glow-up function that moves vm_bo elements back to their original list 🦋 (yes, they get to go home, we love a reunion arc).

---

🌸 SYNOPSIS 🌸

restore_vm_bo_list (__gpuvm , __list_name );

---

🎀 ARGUMENTS 🎀

• __gpuvm — the drm_gpuvm 💖 like, the whole gpu vm situation, that one.
• __list_name — the name of the list we're iterating on ⭐ she's literally the label on the group chat.

---

🔥 DESCRIPTION 🔥

so here's the vibe: when you're done iterating a vm_bo list — like, you've seen everybody, you've said your goodbyes — you should call restore_vm_bo_list to restore the original state and let new iterations take place 🫶

no cap, it's the cleanup step. no lingering weirdness, no half-scrolled list, just a fresh start so the next loop can do its thing 💅✨

and that's the whole page, bestie, you ate that 🍓

mwah 💋 this one lives at ./drivers/gpu/drm, dated October 2026, and yes the header still says restore_vm_bo_list(9) — periodt. 👑🌈
