okay so bestie, this is the glow-up for kvm_gpc_deactivate(9) from the Kernel API Manual — and yes, she’s giving “quietly important kernel API” energy the whole way through 🫶

🌸 NAME 🌸

kvm_gpc_deactivate — deactivate and unlink a gfn_to_pfn_cache.

---

✨ SYNOPSIS ✨

the whole vibe is literally just this:

void kvm_gpc_deactivate (struct gfn_to_pfn_cache *gpc );

---

🎀 ARGUMENTS 🎀

• gpc — a struct gfn_to_pfn_cache object. that’s the cache babe we’re talking about 💅

---

🦋 DESCRIPTION 🦋

This removes a cache from the VM’s list to be processed on MMU notifier invocation. no cap, that’s the whole move — the cache gets deactivated and unlinked, and it’s no longer hanging out on that VM list when the MMU notifier comes through 🌈
