From: David Howells Date: Thu, 13 Nov 2008 23:38:52 +0000 (+1100) Subject: CRED: Wrap task credential accesses in the FAT filesystem X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f0ce7ee3a8ec1e80b6f460983ef1f26e603026f5;p=linux-beck.git CRED: Wrap task credential accesses in the FAT 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.
