💅 kvm_s390_pv_destroy_page(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're in the kernel API girlies now 🫶. this one's a little function with a big job, and honestly? it's giving "quietly doing the most". let's get into it ✨

---

🌸 NAME 🌸

kvm_s390_pv_destroy_page — literally just destroy a guest page. that's the whole assignment. 💀

---

🦋 SYNOPSIS 🦋

int kvm_s390_pv_destroy_page (struct kvm *kvm , unsigned long gaddr );

that's it. two args, one int coming back at you. no cap. ✨

---

🎀 ARGUMENTS 🎀

• kvm — the guest. your main character, the whole reason we're here 👑
• gaddr — the guest address you want to destroy. like, specifically that one 💅

---

🌈 DESCRIPTION 🌈

so here's the vibe. an attempt will be made to destroy the given guest page — that's the first move, that's the plan.

but if that attempt fails? we don't panic, bestie. an attempt is then made to export the page instead. pivot era 🧚

and if both attempts fail — like, the destroy flops AND the export flops — then an appropriate error is returned. not me getting a whole error out of this 😭 but fr fr, that's what happens.

---

⭐ CONTEXT ⭐

may sleep.

like, the function, not you. you should also sleep tho. sleep is iconic 🍓
