📦 version 7.3.1, in nixpkgs unstable

💅 console_srcu_read_lock(9) — from the Kernel API Manual, bestie 🫶

Okay so picture this: you're deep in the kernel printk lore and you need to walk the console list without the whole thing falling apart. That's the vibe. This is page console_srcu_read_lock(9) and it's literally your entry ticket, so let's go ✨

🌸 NAME 🌸

console_srcu_read_lock — register a new reader for the SRCU-protected console list 💖

Like, you're signing the guest book so the console list knows you're in the building. No cap.

✨ SYNOPSIS ✨

int console_srcu_read_lock (void );

🎀 ARGUMENTS 🎀

  • void — no arguments, babe. Nothing to pass in. She takes nothing and she gives you back a cookie. Iconic behaviour honestly.

🦋 DESCRIPTION 🦋

Bestie, the whole point: use for_each_console_srcu to iterate the console list. That's it. That's the assignment. You call this, you do your little stroll through the console list with for_each_console_srcu, and you're golden 💅

⭐ CONTEXT ⭐

Any context. ANY. Fr fr — you can call this from wherever you happen to be vibing. 🌈

🔥 RETURN 🔥

She returns a cookie 🍪 — and you will hand that cookie straight to console_srcu_read_unlock when you're done. Don't lose it, don't eat it, just pass it along. Periodt.

👑 SEE ALSO 👑

Kernel file ./kernel/printk/printk.c, plus the whole squad, in order:

Read them all. Yes, all of them. I said what I said 💀🧚

Lowkey reminder: lock it, iterate it, unlock it with that cookie. Crying over a leaked SRCU reader is not the main character energy we're going for 😭
