mutex_init_with_key(9)

💅 mutex_init_with_key(9) 💅

okay so this is the Kernel API Manual page for mutex_init_with_key, and it's literally about initializing a mutex with a given lockdep key. Bestie, lockdep is in the chat 🫶

✨ NAME ✨

mutex_init_with_key — initialize a mutex with a given lockdep key

🦋 SYNOPSIS 🦋

mutex_init_with_key (mutex , key );

🎀 ARGUMENTS 🎀

• mutex — the mutex that's getting initialized. Yep, that one right there.
• key — the lockdep key that gets associated with the mutex. It's giving “name tag for lockdep” energy, iykyk.

💖 DESCRIPTION 💖

This initializes the mutex to the unlocked state. Slay.

🚨 Not allowed: initializing an already locked mutex. Like… do not do that. The page is very clear on this, and I'm not gonna sugarcoat it.
