Name
utrace_barrier_pid —
synchronize with simultaneous tracing callbacks
Synopsis
__must_check int utrace_barrier_pid ( | struct pid * pid, |
| | struct utrace_engine * engine); |
Arguments
pid
thread to affect
engine
engine to affect (can be detached)
Description
This is the same as utrace_barrier, 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.
