kho_restore_vmalloc(9)

💖 NAME 💖

okay so kho_restore_vmalloc(9) is here, fresh from the Kernel API Manual, and she’s literally the glow-up queen for vmalloc areas. She recreates and populates an area in vmalloc address space from the preserved memory. No cap. 🫶

✨ SYNOPSIS ✨

void * kho_restore_vmalloc (const struct kho_vmalloc *preservation );

🎀 ARGUMENTS 🎀

• preservation — preservation metadata. That’s the whole vibe. 💅

🦋 DESCRIPTION 🦋

Okay so picture this: kho_restore_vmalloc recreates an area in vmalloc address space and populates it with memory that was preserved using kho_preserve_vmalloc. It’s giving “restoration era,” and honestly? Obsessed. ✨

🌸 RETURN 🌸

pointer to the area in the vmalloc address space, NULL on failure.

bestie, failure means NULL — not a cute look, but at least it’s clear. 😭
