UTRACE_SET_EVENTS_PI(9) 					  utrace core API					   UTRACE_SET_EVENTS_PI(9)

NAME
       utrace_set_events_pid - choose which event reports a tracing engine gets

SYNOPSIS
       __must_check int utrace_set_events_pid(struct pid * pid, struct utrace_engine * engine, unsigned long eventmask);

ARGUMENTS
       pid
	   thread to affect

       engine
	   attached engine to affect

       eventmask
	   new event mask

DESCRIPTION
       This is the same as utrace_set_events, but takes a struct pid pointer rather than a struct task_struct pointer. The caller must hold a ref
       on pid, but does not need to worry about the task staying valid. If it's been reaped so that pid points nowhere, then this call returns
       -ESRCH.
