From 0eb790e3a2d872192af8ceff2cabff8594c56440 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 14 Nov 2008 10:38:46 +1100 Subject: [PATCH] CRED: Wrap task credential accesses in the autofs4 filesystem 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.
