In this case a PageActive page is added to the inactivate list and later the
inactive/active stats will get skewed. While the PageActive checks in vmscan
could be removed and potentially dealt with, a skew in the statistics would
be very difficult to detect. Hence this patch deals just with the common case
where a page being marked accessed has just been added to the local pagevec.

After thinking about it some more, I suspect the possible issue
I outlined before should not be an issue in practice.
