Subject: [PATCH] CacheFiles: Fix the documentation to use the correct
	credential pointer names

From: Marc Dionne <marc.c.dionne@...il.com>

Adjust the CacheFiles documentation to use the correct names of the credential
pointers in task_struct.

The documentation was using names from the old versions of the credentials
patches.
