From f4f82994d1ea0cd01058a245985f1eb5e569e6d3 Mon Sep 17 00:00:00 2001 From: Hoang-Nam Nguyen Date: Wed, 16 Apr 2008 21:01:13 -0700 Subject: IB/ehca: Remove tgid checking Pavel Emelyanov mentioned in 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.
