It was Andy.  Andy, can you please verify the latest -git fixes your
setup?  FWIW, I just verified the reported magic numbers and
everything looks kosher to me.

 # ./fstype / /sys /sys/fs/cgroup/memory/
 f_type=0x0000ef53 /
 f_type=0x62656572 /sys
 f_type=0x0027e0eb /sys/fs/cgroup/memory/

Thanks.
