Will be used to do what?  To assign a security context to the inode and to
allow/deny creating it, right?

It looks like the hook also uses the context_inode parameter to assign a
security context to the inode.  Is that correct?  It looks like that's what the
code does, so if you could get the commit messages in sync, that would be
helpful.  I'm actually still not completely sure I'm understanding the intent
here, given that different places say different things.
