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

engine

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.
