From 3b6362b833b9f7a9d4222cf1bb35f99c411abb31 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sat, 2 Sep 2006 21:22:16 +0400 Subject: [PATCH] eligible_child: remove an obsolete ->tgid check It is not possible to find a sub-thread in ->children/->ptrace_children lists, ptrace_attach() does not allow to attach to sub-threads. Even if it was possible to ptrace the task from the same thread group, we can't allow to release ->group_leader while there are others (ptracer) threads in the same group.
