Before this patch libcontainer badly errored out with `invalid argument` or `numerical result out of range` while trying to write to cpuset.cpus or cpuset.mems with an invalid value provided. This patch adds validation to --cpuset-cpus and --cpuset-mems flag along with validation based on system's available cpus/mems before starting a container.
