here is an excerpt:

[root@linuz11 root]# mount -t container -ocpuset cpuset /containers/
[root@linuz11 root]# ls /containers/
cpu_exclusive memory_pressure mems tasks
cpus memory_pressure_enabled notify_on_release
mem_exclusive memory_spread_page releasable
memory_migrate memory_spread_slab release_agent
[root@linuz11 root]# mkdir /containers/1
[root@linuz11 root]# echo 0 > /containers/1/mems
[root@linuz11 root]# echo 0 > /containers/1/cpus
[root@linuz11 root]# sh
sh-2.05b# echo $$ > /containers/1/tasks
sh-2.05b# cat /containers/1/tasks
4325
4326
sh-2.05b# exit
[root@linuz11 root]# ls /containers/1/tasks
/containers/1/tasks
[root@linuz11 root]# rm -rf /containers/1

Ah, I see the second time I typed 'ls /containers/1/tasks' instead of
cat. When I then used cat, the file was empty, and I got an oops just
like Pavel reported. I bet if I solve the problem he reported, then I
solve my problem :)

thanks,
