From: Li Zefan Date: Tue, 4 Mar 2008 22:28:19 +0000 (-0800) Subject: cgroup: fix default notify_on_release setting X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b6abdb0e6ca5c2c0a7caa4131da2af0750927e72;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
