Are these my vm_mpa.c changes to fix the mmap backing object size being incorrect? I'd like to keep track of these changes and what they appear to fix or not. There is still a VM page alias problem that I can readily demonstrate, on a statistical basis, and there is a page corruption problem having to do with mmap'ed objects (ie: the fixes don't fix everything). Knowing what is or isn't fixed by the changes will narrow the scope of my search for the remaining problems (I'm looking when I have time, which unfortuantely isn't very often).
