Oh, I thought you were arguing hypotheticals. This is more serious, that you have some userspace code which depended on the 2.6.8-2.6.29 way of filling that field, and now we're about to break it. Please, would you share what you were doing with the vm_pgoff of an anonymous area? I won't pretend: I am indeed hoping to show that what you were doing before was already broken, so that we can safely go ahead and break it some more!
