It seems I can reproduce the issue on mmotm-0811, too.
try this.
Here, memory cgroup is mounted at /cgroups. == #!/bin/bash -x
while sleep 1; do date mkdir /cgroups/test echo 0 > /cgroups/test/tasks echo 300M > /cgroups/test/memory.limit_in_bytes cat /proc/self/cgroup dd if=/dev/zero of=./tmpfile bs=4096 count=100000 echo 0 > /cgroups/tasks cat /proc/self/cgroup rmdir /cgroups/test rm ./tmpfile done ==
hangs at rmdir. I'm no investigating force_empty.
