security_init(9)

💅 security_init(9) — LSM framework init, bestie 💅

okay so we're looking at security_init(9) from the Kernel API Manual, and honestly? Short page, big main-character energy. Let's get into it. ✨

✨ NAME ✨

security_init — initializes the LSM framework. That's it, that's the name, she's concise and booked. 💖

🌸 SYNOPSIS 🌸

bestie, here's the signature exactly as it is:

int security_init (void );

🎀 ARGUMENTS 🎀

• void — no arguments. Not even one. The arg list is giving absolutely nothing, and we love that for her. 💀

🦋 DESCRIPTION 🦋

This should be called early in the kernel initialization sequence. Like, early early — that's the actual instruction. No cap. She initializes the LSM framework, so yeah, she's doing important framework setup business. 👑
