💖 add_mem_pool(9) 💖

okay so welcome to the glow-up of <rainbow>add_mem_pool(9)</rainbow> from the Kernel API Manual — yes bestie, we're reading kernel docs together and it's gonna slay 🎀

---

✨ NAME ✨

add_mem_pool — literally just adds a memory pool to the allocator. that's the whole vibe, no cap 💅

---

🦋 SYNOPSIS 🦋

void add_mem_pool (struct io_tlb_mem *mem , struct io_tlb_pool *pool );

(yes the spaces before the commas are canon, we don't touch the source, periodt)

---

🌸 ARGUMENTS 🌸

• mem — the Software IO TLB allocator. this is the main character we're handing stuff to 👑
• pool — the memory pool that's about to be added. it's giving "new kid joining the group chat" energy 🫶
