Subject: CRED: Wrap task credential accesses in the JFFS2 filesystem
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3fc678a0e63138f56109ea31850f19b2e29c45b8;p=openwrt%2Fstaging%2Fblogic.git

CRED: Wrap task credential accesses in the JFFS2 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.
