Don't do that :-) While we're on this subject, I haven't actually seen hlist_for_each_entry() code that even *touches* 'pos'. Will people yell at me loudly if I change the prototype of those macros to be: hlist_for_each_entry(tpos, head, member) (Dropping the 'pos' parameter), and updating anything that calls those macros to drop it as well?
