[Devel] [PATCH RH9 28/33] ve: Allow taskstats via netlink in netns

[Andrey Zhadchenko]

From: Vladimir Davydov <vdavydov at parallels.com>

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.
