    ve: Port diff-ve-allow-taskstats-netlink-in-netns
    
    In fact this patch was in 084.9 already, but was committed in kernel-ve,
    so this is a move from kernel-ve to kernel-patches.

    Subject: [vzlin-dev] [PATCH rh6] ve: allow taskstats netlink in netns
    
    This patch adds support for iotop inside containers.
    Task-exit notification isn't pidns aware and isn't required by iotop.
