Was going to say that the indirect call here is not something
I'd be worried about in terms of performance, but it's also kind of
pointless to have them when we have just the single do_work/free_work
callback. And hence it'd reduce the struct footprint, which is always
useful. So yeah, I do think the change makes sense.
