How did we end up with the stupid _or_null prefix there? I think the
functionality is useful, but the naming is way to verbose, especially
given that a list_first_entry or list_last_entry that optimizes away
that one check doesn't seem useful.

Instead of encoding detailed semantics in the name a good kerneldoc
comment is way better.
