Ok. So it is a limitation in libcg and needs to be fixed. Actually blkio.weight_device can have more than one line and I am not sure if any other controller allows that. That might be the reason that original parser thought that there can be only one value per cgroup per file and never took care of multiple values per file case. So we need to fix libcg.
