Hi ALL


> The oldest supported test distribution kernel version is 3.0[1], we don't need these checks.
> If users want to run these cases on old kernel, they can use old release tag.

Here should return directly instead of removing. IOW, the test6 is 
useless. But now it is safe because "grep -q -w "ns" /proc/cgroups" also 
return directly. So I mean to remove this test6 at a separate patch in 
the future or v3.
