H A Ddevice_cgroup.c7a3bb24f Fri May 16 12:22:52 CDT 2014 Tejun Heo <tj@kernel.org> device_cgroup: use css_has_online_children() instead of has_children()

devcgroup_update_access() wants to know whether there are child
cgroups which are online and visible to userland and has_children()
may return false positive. Replace it with css_has_online_children().
