[PATCH 40/59] CRED: Wrap task credential accesses in the RAMFSfilesystem

From: David Howells
Date: Wed Aug 27 2008 - 10:02:21 EST


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.
