From ae8086ce15fdab2b57599d7a3242a114ba4b8597 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 7 Jan 2013 08:51:07 -0800 Subject: [PATCH] cpuset: introduce cpuset_for_each_child() Instead of iterating cgroup->children directly, introduce and use cpuset_for_each_child() which wraps cgroup_for_each_child() and performs online check. As it uses the generic iterator, it requires RCU read locking too. As cpuset is currently protected by cgroup_mutex, non-online cpusets aren't visible to all the iterations and this patch currently doesn't make any functional difference. This will be used to de-couple cpuset locking from cgroup core. Signed-off-by: Tejun Heo Acked-by: Li Zefan --- Reading git-format-patch failed
