Subject: CRED: Wrap task credential accesses in the netrom protocol
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ba95b2353cf1a7f7f236946530ccf5d0ccec6b38;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

CRED: Wrap task credential accesses in the netrom protocol

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.
