You realize that the list helper is even mis-named?
Generally a "pop()" should pop the last entry, not the first one. Or
course, which one is last and which one is first is entirely up to you
since you can add at the tail or the beginning. So even the name is
ambiguous.
So I really think the whole thing was badly implemented (and yes, part
of that was the whole implementation thing).
Doing list_del() by hand also means that you can actually decide if
you want list_del_init() or not. So it's
But again - keep that helper if you want it. Just don't put a badly
implemented and badly named "helper" it in a global header file that
_everybody_ has to look at.
