CRED: Wrap task credential accesses in the Minix filesystem
David Howells [Thu, 13 Nov 2008 23:38:57 +0000 (10:38 +1100)]
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.
