From: David Howells Date: Thu, 13 Nov 2008 23:38:39 +0000 (+1100) Subject: CRED: Wrap task credential accesses in the PowerPC arch X-Git-Tag: firefly_0821_release~16477^2^2~89 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1330deb0f6e89525c8e9fcbd6b13522c9243bfc0;p=firefly-linux-kernel-4.4.55.git CRED: Wrap task credential accesses in the PowerPC arch 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.
