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.
