You are being unfair: after having talked it over with Nick I
resubmitted this patch (not the same), which was added to -mm and
nobody complained then. Then it got thrown out of -mm during the merge
window because of a conflict, and then now I got around to
resubmitting it again.

But you're the boss, if you don't like it it won't go in.  I'll have a
look at the "don't clear PG_uptodate" solution again and see if we can
get an agreement there.
