From 7ed0175a462c4c30f6df6fac1cccac058f997739 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Thu, 10 Nov 2005 17:22:18 +0300 Subject: [PATCH] [PATCH] Don't auto-reap traced children If a task is being traced we never auto-reap it even if it might look like its parent doesn't care. The tracer obviously _does_ care.
