unregister_ftrace_function(9)

💖 NAME 💖

Welcome to the Kernel API Manual entry for unregister_ftrace_function(9) 💅 — the function that unregisters a function for profiling. Yes bestie, it's literally the un-register girlie.

✨ SYNOPSIS ✨

int unregister_ftrace_function (struct ftrace_ops *ops );

🎀 ARGUMENTS 🎀

• ops — the ops structure that holds the function you wanna unregister. That's the whole vibe 🫶

🦋 DESCRIPTION 🦋

okay so bestie, here's the tea: this unregisters a function that was added to be called by ftrace profiling. That's it. That's the whole moment. You hand it the ops structure that holds the function to unregister, and it does the unregistering thing. No cap ✨
