Did you mean me? My code seems to work now, and strace says: fstatfs(6, {f_type=0x27e0eb, f_bsize=4096, f_blocks=0, f_bfree=0, f_bavail=0, f_ files=0, f_ffree=0, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) = 0 which is consistent with: #define CGROUP_SUPER_MAGIC 0x27e0eb This is on master. I'll test next eventually. Thanks everyone! --Andy
