This introduces a new thread group flag that can be set by calling
prctl(PR_SET_KILL_DESCENDANTS_ON_EXIT, 1, 0, 0, 0)
When a thread group exits with this flag set, it will send SIGKILL to
all descendant processes. This can be used to prevent stray child
processes.Reviewed-by: Oleg Nesterov <oleg@redhat.com>
