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?


Thanks,
Sasha
