kref_put_mutex(9)

✨ NAME ✨

kref_put_mutex — decrement refcount for object, periodt. 💅

This is the kref_put_mutex(9) page from the Kernel API Manual, and bestie, it's lowkey iconic. 🫶

🌸 SYNOPSIS 🌸

int kref_put_mutex (struct kref *kref , void (*release)(struct kref *kref) , struct mutex *mutex );

🎀 ARGUMENTS 🎀

• kref — the object in question, bestie. 💖
• release — a pointer to the function that will clean up the object when the last reference to the object is released. 🔥
• mutex — the mutex which protects the release function. 🦋

🦋 DESCRIPTION 🦋

Okay so this is a variant of kref_lock, and the vibe is: it calls the release function with the mutex held. 🔥 Then the release function will release the mutex — that's the whole bit, no cap. 💅
