NAME

6       utrace_barrier_pid - synchronize with simultaneous tracing callbacks
7

SYNOPSIS

9       __must_check int utrace_barrier_pid(struct pid * pid,
10                                           struct utrace_engine * engine);
11

ARGUMENTS

13       pid
14           thread to affect
15
16       engine
17           engine to affect (can be detached)
18

DESCRIPTION

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