    I'm assuming you actually meant printf() (which is the userspace stdio call)
    rather than printk() (which is the inside-the-kernel variant).

    'man setbuf' - most likely the output of the child process is buffered and
    never actually output before it exits. You want to set stdout to be
    line-buffered or unbuffered, or write to stderr (unbuffered by default) rather
    than stdout.
