Yeah, it probably would make sense. Especially as doing a simple grep for 
'list_entry.*prev' does seem to imply that there might be quite a few 
places that would be able to use it. Although some of them do seem to be 
about finding the previous entry rather than the last in a list.

That said, doing the same grep for 'next' shows that a lot of places don't 
use the list_first_entry() that we _do_ have, so..
