From ebca4cda1133775111e8b09f7124a7e5e391926d Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 16 Oct 2007 23:26:59 -0700 Subject: zap_other_threads: don't optimize thread_group_empty() case Nowadays thread_group_empty() and next_thread() are simple list operations, this optimization doesn't make sense: we are doing exactly same check one line below.
