From 247284481ca40288bd120cf0707681c3bdbee78f Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sat, 4 Aug 2007 01:04:41 +0400 Subject: [PATCH] Kill some obsolete sub-thread-ptrace stuff There is a couple of subtle checks which were needed to handle ptracing from the same thread group. This was deprecated a long ago, imho this code just complicates the understanding. And, the "->parent->signal->flags & SIGNAL_GROUP_EXIT" check in exit_notify() is not right. SIGNAL_GROUP_EXIT can mean exec(), not exit_group(). This means ptracer can lose a ptraced zombie on exec(). Minor problem, but still the bug.
