Ok, I see. Recent kernels directly mount "cpuset" as "cgroup" but they add the "noprefix" mount option to maintain backward compatibility with the old /dev/cpuset/ filenames. We need to either check whether noprefix is given in the mount options, or directly look for cpus/mems if cpuset.cpus/cpuset.mems do not exist. I'll fix this when after some testing. thanks, Brice
