Yes. md_flush_mddev should simply be removed. The functionality should be, and largely is, in the individual personalities.
Is there documentation somewhere on exactly what an issue_flush_fn should do (is it allowed to sleep? what must happen before it is allowed to return, what is the "error_sector" for, that sort of thing).
I suspect that at least raid5 will need some fairly special handling.
