Subject: util: vircgroupv2: use any controller to create thread directory
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=535bdf83c0b0372e725650c56b4996ff83406254;p=libvirt.git

util: vircgroupv2: use any controller to create thread directory

The assumption that CPU controller would be always enabled is wrong, we
should use any available controller to create a new sub-cgroup.
