Hi Christoph,
Could you pull my XFS wrapper patch into the XFS tree? That might make things
easier for Stephen. The prerequisite patch is already upstream. Now if only
Linus would take the rest of it.

CRED: Wrap task credential accesses in the XFS 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.
