🌸 __pte_alloc_one_kernel(9) — Kernel API Manual 🌸

Okay bestie, we're doing the Kernel API Manual page for __pte_alloc_one_kernel(9) and it's giving very specific kernel-page-table energy. Let's go. 💅

✨ NAME ✨

__pte_alloc_one_kernel — allocate memory for a PTE-level kernel page table

🎀 SYNOPSIS 🎀

pte_t * __pte_alloc_one_kernel (struct mm_struct *mm );

🫶 ARGUMENTS 🫶

• mm — the mm_struct of the current context.

💅 DESCRIPTION 💅

This one is meant for architectures that need anything beyond simple page allocation.

Like, it's not the "just do the simplest possible page allocation" situation — it's specifically for architectures that need anything beyond that. That's the whole note. 💖

🔥 RETURN 🔥

You get back a pointer to the allocated memory, or NULL on error.
