💅 free_pt(9) — Kernel API Manual, group-chat edition ✨

okay so bestie, this is the Kernel API Manual page for free_pt, and it's lowkey a short bop. It's the custom page table free function — cleanup main character energy, fr fr. Let's do a vibe check on every detail, no cap.

💖 NAME 💖

free_pt — Custom page table free function

✨ SYNOPSIS ✨

the whole signature, copied exactly because we respect code in this house 🫶:

void free_pt (void *cookie , void *data , size_t size );

🌸 ARGUMENTS 🌸

• cookie — the cookie passed at page table allocation time. yes, that cookie. 🍪
• data — the page table to free. bye bestie, it's giving cleanup 👋
• size — size of the page table. and hear me out: this size should be fixed, and determined at creation time based on the granule size. that part is important, ngl 💅
