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.
