My colleague Jeff Squyres from the Open MPI project posted a blog entry about why MPI wants this: http://blogs.cisco.com/ciscotalk/performance/comments/better_linux_memory_tracking/ His summary of ummunotify: "It’s elegant, doesn’t require strange linker tricks, and seems to work in all cases. Yay!" This code went through several review iterations on lkml and was in -mm and -next for quite a few weeks.
