Just to verify - can you confirm that this "just fixes it" for you?

I think this is the right approach to take, and seems very safe (ie people
who know that their loads are ok can just set the flag), but I do want to
verify that there was nothing else going on, and that you now see the same
performance as you did in 2.6.16?

The other alternative, of course, would be to simply allow the dirty
percentages to be > 100%, but that's just *odd* ;)
