We still have a main object that is simply a list of ACEs.  But if that
doesn't work out (I suspect it should) I don't think the common base
object is a good idea.  It just leads to a lot of crazy container_of
calls.  If the common object abstraction doesn't work out we'll need
a procedural one instead that has common acl_* calls that decide what
do to based on the file system acl flag.
