IB/ehca: Remove tgid checking
Pavel Emelyanov <xemul@openvz.org> mentioned in <http://lkml.org/lkml/2008/3/17/131> that the task_struct->tgid field is about to become deprecated, so the uses in the ehca driver need to be fixed up. However, all the uses in ehca are for some object ownership checking that is not really needed, and anyway is implementing a policy that should be in common code rather than a low-level driver. So just remove all the checks. Signed-off-by: Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
