Yes.

That's not what I was thinking of. I was thinking of something much simpler:
struct foo { struct timer_list timer; };
... struct foo *a = kmalloc(sizeof(struct foo), GFP_KERNEL); a->timer.fn = do_foo_timer; ... struct foo *b = kmalloc(sizeof(struct foo), GFP_KERNEL); b->timer.fn = do_foo_timer; ... struct foo *c = kmalloc(sizeof(struct foo), GFP_KERNEL); c->timer.fn = do_foo_timer; ... struct foo *d = kmalloc(sizeof(struct foo), GFP_KERNEL); d->timer.fn = do_foo_timer; ...
You've now got four copies of struct timer_list, but only one handler.
