event_trigger_unregister(9)

💖 NAME

event_trigger_unregister — unregister an event trigger ✨

Hey bestie, welcome to the event_trigger_unregister(9) page from the Kernel API Manual 🫶 this function is literally here to unregister an event trigger. Short, sweet, iconic.

✨ SYNOPSIS

void event_trigger_unregister (struct event_command *cmd_ops , struct
trace_event_file *file , char *glob , struct event_trigger_data
*trigger_data );

The signature is giving “yes I’m compact, yes I’m powerful” 💅

🎀 ARGUMENTS

• cmd_ops — the event_command operations for the trigger 🛠️
• file — the event file for the trigger's event 📁
• glob — the trigger command string, with optional remove(!) operator 🫧
• trigger_data — the trigger_data for the trigger 🎯

🌸 DESCRIPTION

Unregister an event trigger. The cmd_ops are used to call the cmd_ops->unreg function which actually does the unregistration 😌 so yeah, cmd_ops is not the main character doing the work — it’s the one calling cmd_ops->unreg, and that function is where the actual unregistration happens. Periodt 💖
