💅 ttm_pool_drop_backed_up — kernel API manual, but make it cute

okay so bestie, the page header is ttm_pool_drop_backed_up(9) and the manual is the Kernel API Manual — and today's main character is ttm_pool_drop_backed_up, a tiny little function that does one job and does it iconically ✨

---

🌸 NAME 🌸

ttm_pool_drop_backed_up — release the content of a swapped-out struct ttm_tt

like, it's a cleanup function. it drops stuff. it's giving responsible queen 💅

---

🎀 SYNOPSIS 🎀

void ttm_pool_drop_backed_up (struct ttm_tt *tt );

yes that's the whole signature, no cap, it returns void (nothing back, just vibes) 🫶

---

✨ ARGUMENTS ✨

• tt — the struct ttm_tt. that's it. that's the argument. it's the struct, the one and only, the main character of this function 🎯

---

🦋 DESCRIPTION 🦋

So basically: this function releases the handles with their associated content, or any remaining pages, of a backed-up struct ttm_tt. 🧹

let me say that again because it ate: handles with associated content → released. any remaining pages of a backed-up struct ttm_tt → also released. it's a whole cleanup situation and she handles both cases, periodt. 🔥
