    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.
