From 241ceee0b442c69226fb882d61d9b9785743898f Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sun, 24 Dec 2006 23:30:44 +0300 Subject: [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 To: Albert Cahalan Cc: Eric W.
