From b6abdb0e6ca5c2c0a7caa4131da2af0750927e72 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Tue, 4 Mar 2008 14:28:19 -0800 Subject: cgroup: fix default notify_on_release setting The documentation says the default value of notify_on_release of a child cgroup is inherited from its parent, which is reasonable, but the implementation just sets the flag disabled.
