swiotlb_del_pool(9)

🌸 NAME 🌸

okay so bestie, welcome to the swiotlb_del_pool(9) page from the Kernel API Manual 💖 this one is short and sweet: swiotlb_del_pool — remove an IO TLB pool from a device. that's it, that's the whole main-character job. ✨

✨ SYNOPSIS ✨

void swiotlb_del_pool (struct device *dev , struct io_tlb_pool *pool );

copy it exactly, spacing and all — the return type is void, so don't go looking for a return value, bestie 💅

🎀 ARGUMENTS 🎀

• dev — the owning device. like, the device that owns the pool 🫶
• pool — the memory pool to be removed. it's getting del'd, fr fr 👋
