🌸 SYNOPSIS 🌸

void ptdesc_set_kernel (struct ptdesc *ptdesc );

🎀 ARGUMENTS 🎀

  • ptdesc — the ptdesc you're marking, that's it, that's the whole argument, love that for us 🫶

🦋 DESCRIPTION 🦋

so, kernel page tables? they lowkey need special handling, like they're the main character and everyone else is just living in their world 💅.

this function sets a flag, and the flag is basically telling the handling code: "hey bestie, this ptdesc is NOT for userspace" ✨. so the code that handles it knows exactly what vibe it's dealing with and doesn't get confused. no cap.

ngl it does one thing and it does it well. iconic behaviour fr fr 🎀
