I'm looking at the original reproducer at: https://lists.openvz.org/pipermail/devel/2009-January/016345.html And as far as I can tell the test_5() was never actually doing what it takes to reproduce the bug, as far as I can tell the test was bogus to begin with. The main point of the reproducer is that the cgroup is unmounted while there is task in the group, then remounted again. As we cannot unmount the cgroup these days I would just go for removing the test instead of applying band aid over the code. -- Cyril Hrubis chrubis@suse.cz
