This code is just maintaining the order that policies were registered. Whether or not this has anything to do with module dependencies is up to the caller of mac_policy_register(). The comment could explain this more clearly.

Yes, this looks like it's really just a cleanup of the order in the list. sjg originally did the change. I'll adjust the commit log.

The last revision just deleted the comment. It would be better to note somewhere that the insertion order actually matters.
