Hi, I have Fedora 23 with kernel 4.2.3-300.fc23.x86_64 out of the box. Sytsemd mounts the memory controller on /sys/fs/cgroup/memory I am trying the following sequence: mkdir /memCgroupTest1 mount -t cgroup -o memory memtest1 /memCgroupTest1 It succeeds. Also after creating subfolders in /memCgroupTest1, the set of control files for memory controller + the generic files is created. Mounting the memory controller again on other folders under / also succeeds. When I try it with other controllers like cpu/net_prio it fails. It seems to me that we should not be permitted to mount the memory controller more than once while it is mounted also elsewhere. Is this a BUG or an expected behavior ?
