From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alan Cox Subject: [PATCH 29/75] CRED: Wrap task credential accesses in the devpts filesystem Date: Fri, 02 Jan 2009 13:44:49 +0000 Message-ID: <20090102134440.13472.54949.stgit@localhost.localdomain> References: <20090102133822.13472.53912.stgit@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from earthlight.etchedpixels.co.uk ([81.2.110.250]:37594 "EHLO lxorguk.ukuu.org.uk" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1756961AbZABNqU (ORCPT ); Fri, 2 Jan 2009 08:46:20 -0500 In-Reply-To: <20090102133822.13472.53912.stgit@localhost.localdomain> Sender: linux-serial-owner@vger.kernel.org List-Id: linux-serial@vger.kernel.org To: torvalds@osdl.org, linux-serial@vger.kernel.org From: David Howells Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.
