| From | David Howells <> | Subject | [PATCH 26/59] CRED: Wrap task credential accesses in the FAT filesystem | Date | Wed, 27 Aug 2008 14:47:56 +0100 |
| |
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.
