select_unwinder(9)

💅 pick your unwinder, bestie: select_unwinder(9) 💅

okay so bestie, welcome to select_unwinder(9) from the Kernel API Manual — the page where the kernel picks its favorite registered stack unwinder. It’s short, it’s private, and it’s lowkey iconic. Let’s go ✨

🎀 NAME 🎀

select_unwinder — select the best registered stack unwinder. That’s the whole name and the whole job, no cap. 👑

✨ SYNOPSIS ✨

struct unwinder * select_unwinder (void );

🦋 ARGUMENTS 🦋

• void — no arguments. Literally none, bestie, not even one. 🫶

💖 DESCRIPTION 💖

okay so this one is a private function — private, private, iykyk. You must hold unwinder_lock when called. Like, do not skip the lock, fr fr. 🔒

It selects the stack unwinder with the best rating. That’s the vibe check: best rating wins. This is useful for setting up curr_unwinder, so the kernel knows which unwinder is the main character. 👑
