NAME
utrace_barrier_pid - synchronize with simultaneous tracing callbacksSYNOPSIS
- __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.
