    signal: Use group_send_sig_info to kill all processes in a pid namespace · 82058d66
    Eric W. Biederman authored
    Replace send_sig_info in zap_pid_ns_processes with
    group_send_sig_info.  This makes more sense as the entire process
    group is being killed.  More importantly this allows the kill of those
    processes with PIDTYPE_MAX to indicate all of the process in the pid
    namespace are being signaled.  This is needed for fork to detect when
    signals are sent to a group of processes.
    Admittedly fork has another case to catch SIGKILL but the principle remains
    that it is desirable to know when a group of processes is being signaled.
