From d4f7c511c1c2a67eb287987cf1ce9554149030e6 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 22 Jun 2011 23:10:11 +0200 Subject: do not change dead_task->exit_signal __ptrace_detach() and do_notify_parent() set task->exit_signal = -1 to mark the task dead. This is no longer needed, nobody checks exit_signal to detect the EXIT_DEAD task.
