✨ free_iova(9) ✨

okay so bestie, welcome to the free_iova page 💖 this one lives in the Kernel API Manual and it's basically the cleanup crew — it finds and frees the iova for a given pfn 🎀

🌸 NAME 🌸

free_iova — finds and frees the iova for a given pfn ✨

🦋 SYNOPSIS 🦋

void free_iova (struct iova_domain *iovad , unsigned long pfn );

💅 ARGUMENTS 💅

• iovad — the iova domain in question, like, the actual domain we're doing business in 🫶
• pfn — the pfn that is allocated previously. This function finds an iova for a given pfn and then frees the iova from that domain 💀✨ (yes it does both things, it's an overachiever, main character energy fr fr)
