💖 NAME 💖

okay so bestie, we're in the Kernel API Manual and this page is get_kernel_nofault(9) — and yes, the name is literally get_kernel_nofault, and its whole thing is: safely attempt to read from a location. That's the vibe. ✨

✨ SYNOPSIS ✨

get_kernel_nofault (val , ptr );

That spacing? exactly as printed. Don't come for the synopsis, it's iconic. 💅

🎀 ARGUMENTS 🎀

• val — read into this variable. Yep, this is where the read lands. 🫶
• ptr — address to read from. This is the address, bestie. 📍
