If @pidfd referes to a thread then the signal is thread directed. No, this depends on PIDFD_THREAD only. If it is set then the signal is always "thread directed" even if @pidfd refers to a thread-group leader. Otherwise the target task must be a group leader and the signal will be "thread-group directed". Right? Oleg.
