It makes sense to roll that fix in with the stuff you're doing.

If it's going to be a little while before your patches get taken into
mainline though, it might not hurt to go ahead and push my patch in as
an interim fix. It shouldn't change the behavior of the code in the
normal case of a short-lived dirtied_when value, and should guard
against major problems when there's a long-lived one.
