Subject: CRED: Wrap task credential accesses in the PA-RISC arch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25e15731af0c8d7adc58f72327dab7293857129f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

CRED: Wrap task credential accesses in the PA-RISC arch

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.
