[patch 2/2] Use find_task_by_vpid in audit code
The pid to lookup a task by is passed inside audit code via netlink message. Thanks to Denis Lunev, netlink packets are now (since 2.6.24) _always_ processed in the context of the sending task. So this is correct to lookup the task with find_task_by_vpid() here. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Cc: "Eric W.
