Subject: Re: [PATCH 00/52] Introduce credential record

Hi David,
I'm going to ask a stupid question, and I probably missed something
in the 52 patches, but.... I see how the credential is used to do
access checks, but why does the credentials record need to passed all
the way into block allocator? What is it used for there?
