Sorry for the long delay in getting to these.  I week's leave recently
and that always causes tasks to pile up....

I am happy for this to  all go in this merge window.  I just have a
few nits I would like to see changed then I'll pull and push to Linus.

in this patch:
>  		/* now count some things */
>  		if (test_bit(R5_LOCKED, &dev->flags)) s.locked++;
>  		if (test_bit(R5_UPTODATE, &dev->flags)) s.uptodate++;
> +		if (test_bit(R5_Wantcompute, &dev->flags))
> +			BUG_ON(++s.compute > 2);

I think having a side-effect in a BUG_ON is very poor form.  I should
be able to recompile the code with BUG_ON() becoming a no-op and
everything should still work.
So something like:
> +		if (test_bit(R5_Wantcompute, &dev->flags)) {
> +			++s.compute;
> +			BUG_ON(s.compute > 2);
> +		}

please.
