[PATCH] restore ->pdeath_signal behaviour
Commit b2b2cbc4b2a2f389442549399a993a8306420baf introduced a user- visible change: ->pdeath_signal is sent only when the entire thread group exits. While this change is imho good, it may break things. So restore the old behaviour for now. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> To: Albert Cahalan <acahalan@gmail.com> Cc: Eric W.
