This patch worked fine in my test case, but I have one question about
your patch. I assume that you added refresh_filters() because it was
necessary, but this patch prevents filter from being refreshed if it
is in use.

Don't we need to refresh the filter when in_use flag is decremented
and becomes 0 after or in dev_iter_destroy()?

Thanks,
Taka
