Carried: #14015 If kernel is compiled with CONFIG_FAIR_GROUP_SCHED disabled cpu.shares doesn't exist. If kernel is compiled with CONFIG_CFQ_GROUP_IOSCHED disabled blkio.weight doesn't exist. If kernel is compiled with CONFIG_CPUSETS disabled cpuset won't be supported. We need to handle these conditions by checking sysinfo and verifying them.
